Custom targets as sources to `gnome.gdbus_codegen` worked until version 0.60
of Meson, but broke in 0.61 because of the conversion to typed_pos_args
and typed_kwargs. Reinstate this by adding custom targets to the
decorators and annotations.
While generators also used to work, they are a bit tricky because
gdbus_codegen desugars to two custom_targets and therefore the generator
is invoked twice. This should not be a problem, but be explicit and
leave that to a separate commit to highlight the problem.

Fixes: ef52e6093 ("modules/gnome: use typed_kwargs for gdbus_codegen", 2021-11-08)
ccache was used in all command lines but disabled using CCACHE_DISABLE
in Compiler.compile() method. Wrapping invokations still has a cost,
especially on Windows.
With sccache things are even worse because CCACHE_DISABLE was not
respected at all, making configure *extremely* slow on Windows when
sccache is installed.
Move `detect_native_windows_arch()` to `mesonlib/universal.py` and
rename it to `windows_detect_native_arch()`
Use `IsWow64Process2()` to detect native architecture if available
Use native `vcvarsarm64.bat` to initialize vsenv if available
This is based on searching for `@FeatureNew*` decorators.
There is also one correction to a version in a decorators;
`build_by_default` was added in #1303, which is 0.38.0, not 0.40.0.
We accept a list of known kwargs of required types, but also arbitrary
kwargs understood by the hotdoc program (sometimes via extensions). Now
that we can partially type-check kwargs, do so here.
Some functions cannot be fully type checked, because our API allows
fully arbitrary kwargs and treats them as data to pass through to the
underlying feature. For example, hotdoc command line arguments.
This change allows us to type check some kwargs with known types and
possibly required status, and make their values consistent(ly defaultable),
while preserving the optional nature of the additional kwargs.
If those files are not yet known to be typed, skip them. This makes it
possible to trivially check a shortlist of files that were just changed
and see if they regress our mypy coverage. Ideal for use in a git
pre-commit hook.
Since vs backend only support the C compiler, everything else are custom
targets. Convert CompileTarget into a Generator to reuse existing code.
This will be useful in the future to support transpilers, and
assemblers.
This introduce a new type of BuildTarget: CompileTarget. From ninja
backend POV it is the same thing as any other build target, except that
it skips the final link step. It could be used in the future for
transpilers too.
When using both_libraries(), or library() with default_library=both, we
remove all sources from args and kwargs when building the static
library, and replace them by the objects from the shared library. But
sources could also come from any InternalDependency, in which case we
currently build them twice (not efficient) and link both objects into
the static library.
It also means that when we needlessly build those source for the static
library, it miss order dependency on generated headers that we removed
from args/kwargs, which can cause build errors in the case the source
from static lib is compiled before the header in shared lib gets
generated.
This happened in GLib:
https://gitlab.gnome.org/GNOME/glib/-/merge_requests/2917.
cc.compiles(), and other compiler checks that use cc.compiles() under
the hood, do not use link args at all when doing the compile check, so
messages like this:
```
Checking if "have zlib" with dependency -lz compiles: YES
```
is very misleading. The compiler check command-line for that is:
```
cc [...]/testfile.c -o [...]/output.obj -c -D_FILE_OFFSET_BITS=64 -O0
```
Note the lack of linker args.
