Even though Makefile generators pass source files and include
directories by absolute path to the compiler, the compiler may generate
depfile paths relative to the current working directory. For example,
`ccache` with `CCACHE_BASEDIR` may transform paths this way. When
reading a depfile, convert relative dependencies to absolute paths
before placing them in `compiler_depend.make`, which is later evaluated
in the top-level build directory.

Refactoring in commit 7f506b95a7 (cmGeneratorTarget: Refactor link item
lookup, 2021-05-26, v3.21.0-rc1~103^2~4) accidentally dropped the
persistent lookup scope tracking across multiple items that was added by
commit f0e67da061 (target_link_libraries: Fix out-of-dir linking of a
list of targets, 2020-01-14, v3.17.0-rc1~149^2). This broke a
transitive out-of-dir linking case not covered by our test suite.
Restore the scope tracking and add a test case.

In commit 4ea3a88625 (MSVC: Add support for targeting ARM64EC,
2020-12-30, v3.20.0-rc1~121^2) the `ARM64EC` platform was accidentally
added to the list for VS 15 (2017) instead of VS 16 (2019). Its
omission from the list of platforms was then repeated for VS 17 (2022).

Visual Studio 17 2022 is now a 64-bit native application. It places the
64-bit `MSBuild.exe` in the `PATH` of VS command prompts, so prefer it
for this version and above.
This was previously attempted for older VS versions, but reverted by
commit f3cedf381e (VS: Revert "Use MSBuild matching toolset host
architecture", 2019-03-12, v3.14.0~1^2). For now, do not use the 64-bit
MSBuild for VS 16 and below.

Since commit 887e9df0c7 (VS: Update v142 CL flag table for VS 16.10,
2021-06-04) we map several `/external:*` flags to their corresponding
`.vcxproj` elements. These elements were added to `cl.xml` in VS 16.10,
so filter them out in older VS versions. Add a field to the json flag
table format to specify the minimum version of VS needed for a given
mapping.
Issue: #22308
Since commit 9054cd05e6 (VS: Add flag table entries for '/external:W*'
flags in VS 16.10, 2021-05-28, v3.20.4~10^2) we map flags to the
`ExternalWarningLevel` element. VS 16.9 does not support that element,
but its `cl` compiler does support the `/external:W*` flags. Filter out
the flag table entry on older VS versions.

When scanning Fortran dependencies, we know the file path at which a
provided module file is written. Store it in the `compiled-module-path`
field as specified by P1689R4. Our collator in `cmake_ninja_dyndep` no
longer needs to assume that the module file path can be derived from the
logical module name. In the future, the Fortran dependency scanning may
be done by the compiler itself, in which case it will provide the value
of `compiled-module-path`.
Read and write the `compiled-module-path` field only when explicitly
known. Move the assumption that the `compiled-module-path` can be
derived from the logical module name from the scandep parser to the
`cmake_ninja_dyndep` helper.
When running the module dependencies scan tool for for a language that
does not compile the preprocessed output, we do not actually put the
preprocessed output in the build graph. However, the value of
`CMAKE_EXPERIMENTAL_<LANG>_SCANDEP_SOURCE` may reference the placeholder
for the preprocessed source. Populate the placeholder to keep the file
out of the way. In particular, do not clobber the `.ddi` file.
Since commit 33a8e0bb09 (cmNinjaTargetGenerator: Simplify scan rule
depfile selection, 2020-11-06, v3.20.0-rc1~516^2~1), the `$out` of the
scan rule always matches our `.rsp` file selection, so use `$out.rsp`.
