this adds support for generating pkgconfig files for c#.
The difference to c and cpp is that the -I flag is not known to the c#
compiler, but rather the -r flag which is used to link a .dll file into
the compiled library.
However this opens the question of validating which pkgconfig files can
be generated (depending on the language).
This implements 4409.
Be more prescriptive about the static linker to use in test case
common/143. This avoids using DMD's 'lib' in preference to clang-cl's
'llvm-lib' when both of them are in PATH
Resolves segfaults on i686 kernel. Also execute all available simd
instructions, not just the best one.

Because we are racing here. In reality *all* of the java in that target
may rely on the generated file, so we need to block all of them, like we
would for headers in C/C++.
When trying to cross-compile mesa on an aarch64 system, I noticed some
strange behavior. Meson would only ever find the wayland-scanner binary
in my host machine's sysroot (/mnt/amethyst):
Native dependency wayland-scanner found: YES 1.16.0
Program /mnt/amethyst/usr/bin/wayland-scanner found: YES (/mnt/amethyst/usr/bin/wayland-scanner)
It should be finding /usr/bin/wayland-scanner instead, since the
wayland-scanner dependency is created as native. On closer inspection,
it turned out that meson was ignoring the native argument passed to
dependency(), and wuld always use the pkgconfig binary specified in my
toolchain instead of the native one (/usr/bin/pkg-config):
Native dependency wayland-scanner found: YES 1.16.0
Called `/home/lyudess/Projects/panfrost/scripts/amethyst-pkg-config
--variable=wayland_scanner wayland-scanner` -> 0
Turns out that if we create a dependency() object with native:false, we
end up caching the pkg-config path for the host machine in
PkgConfigDependency.class_pkgbin, instead of the build machine's
pkg-config path. This results causing in all pkg-config invocations for
dependency() objects to use the host machine's pkg-config binary,
regardless of whether or not 'native: true' was specified when the
dependency() object was instantiated.
So, fix this by never setting PkgConfigDependency.class_pkgbin for cross
dependency() objects. Also, add some test cases for this. Since
triggering this bug can be avoided by creating a dependency() objects
with native:true before creating any with native:false, we make sure
that our test has two modes: one where it starts with a native
dependency first, and another where it starts with a cross dependency
first.
As a final note here: We currently skip this test on windows, because
windows doesn't support directly executing python scripts as
executables: something that we need in order to point pkgconfig to a
wrapper script that sets the PKG_CONFIG_LIBDIR env appropriately before
calling pkg-config.

Deal with clang-cl doing the sane (but different to MSVC) thing, of
generating an empty import library, rather than silently ignoring
/IMPLIB when there are no exports.
It's a (presumably unintentional) quirk of the current implementation of
SharedLibrary.determine_filenames() that if both name_suffix and
name_prefix are set, an import library isn't generated.
Adjust test 'common/25 library versions': Make the library have exports,
so an implib is generated with MSVC. Add implib to set of files expected
to be installed
Adjust test 'common/122 shared module': Add libnosyms implib to set of
files expected to be installed, except for MSVC, where none is generated
as it has no exports
Extend platform_fix_name() to handle this case
We avoid using library(version:), so we don't have to teach
platform_fix_name() all the platform details of versioned shared library
naming. Hopefully that's exercised by platform-specific tests...
'test cases/common/123 llvm ir and assembly' requires ML/ML64 (masm) on
Windows. If we are using clang-cl, that might not be available, so skip
test in that case.
clang-cl does support '-Wmissing-include-dirs' (unlike msvc), but doesn't
(currently) support '/ZI' (which is used by the default 'debug' buildtype),
the presence of which will cause an 'unknown-argument' warning, which is
treated as an error with 'Werror'.
Adjust the default buildtype so this test can pass with clang-cl
Rewrite test common/100 manygen using get_argument_syntax(), so it
treats clang-cl as cl, can handle only clang-cl being available, and try
to make it a bit less convoluted.
Handle clang's cl or clang-cl being in PATH, or set in CC/CXX
Future work: checking the name of the executable here seems like a bad idea.
These compilers will fail to be detected if they are renamed.
v2:
Update compiler.get_argument_type() test
Fix comparisons of id inside CCompiler, backends and elsewhere
v3:
ClangClCPPCompiler should be a subclass of ClangClCCompier, as well
Future work: mocking in test_find_library_patterns() is effected, as we
now test for a subclass, rather than self.id in CCompiler.get_library_naming()
Some compilers try very had to pretend they're another compiler (ICC
pretends to be GCC and Linux and MacOS, and MSVC on windows), Clang
behaves much like GCC, but now also has clang-cl, which behaves like MSVC.
This method provides an easy way to determine whether testing for MSVC
like arguments `/w1234` or gcc like arguments `-Wfoo` are likely to
succeed, without having to check for dozens of compilers and the host
operating system, (as you would otherwise have to do with ICC).
If a subproject is not required and fails during its configuration, the
parent project continues, but should not include any target or state set
by the failed subproject. This fix ninja still trying to build targets
generated by subprojects before they fail in their configuration.
The 'build' object is now per-interpreter instead of being global. Once
a subproject interpreter succeed, values from its 'build' object are
merged back into its parent 'build' object.
When dependency(), find_library(), find_program(), or
python.find_installation() return a not-found object and disabler is
true, they return a Disabler object instead.
