When the proc-macro rlib is in a different subdir, it would miss the
needed -L argument and rustc would not find it. Meson was assuming that
proc-macros are only needed when building libraries that uses it, but it
turns out that was wrong, as show by the unit test.
* `-Wpedantic` creates useless churn due to its use of gcc-line directives:
../foo.cu:1:3: warning: style of line directive is a GCC extension

Cargo implements this configuration option to override the entry point
of the library.
To get test coverage, I've modified one of the two Cargo subprojects
in the test to use a non-default library entrypoint. The other still
uses the default.
Alterations to kwargs come in two flavors:
1. Remove/replace values (delete/set)
2. Modify values (add/remove)
Only for the second flavor do we care about the type of any existing
value.
Currently, not only Meson lacks a way to induce a "--fatal-warnings" on
LINK.exe, it is also unable to pass flags appropriately when using
clang-cl or Microsoft's stock clang.
This commit fixes it by implementing `fatal_warnings()` in the
MSVCDynamicLinker and ClangCLDynamicLinker classes, and by implementing
the requisite conversion steps in linker_to_compiler_args for
ClangCompiler.
This way the `rust.bindgen` can generate a second output being a C file,
which contains wrapper functions for static inline ones.
This output file can then be compiled via C targets.
Followup to 7b7d2e060b which handles ASAN and UBSAN.
It turns out that MSAN needs the same treatment. I've checked other sanitizers
like HWASAN and TSAN - it looks like they may both need it too, but Meson doesn't
currently suppose those anyway (see https://github.com/mesonbuild/meson/pull/12648).

These are much easier to handle as one commit since msetup calls mconf
internally. This has found one case where things are being carefully
crafted to work in mconf even though msetup has slightly different
options
Instead of being instance state, it's passed around. This isn't a big
deal internally since most of the users are protected, and the only time
an external change is required is a couple of places in msubprojects,
which is fine because the information is available.
