Use ELF headers vendored in `Utilities/cmelf` to get the ELF constants
and types. Using the same ELF definition header for all compilation
targets allows removing some #ifdefs depending on the host OS since we
know all required ELF constants will always be present. To reduce the
size of this commit, the CMake_USE_ELF_PARSER definite will be removed
in a separate commit.
This allows me to use CMAKE_BUILD_WITH_INSTALL_RPATH=False and the Ninja
generator on macOS, whereas before it would always give me the following
error message (despite cross-compiling for an ELF-based platform):
```
The install of the <name> target requires changing an RPATH from
the build tree, but this is not supported with the Ninja generator unless
on an ELF-based platform. The CMAKE_BUILD_WITH_INSTALL_RPATH variable may
be set to avoid this relinking step.
```
DT_MIPS_RLD_MAP_REL is a machine-speicific dynamic tag, so other
architectures could re-use the value of 0x70000035 to mean something
else. Before using DT_MIPS_RLD_MAP_REL, we have to check that the ELF
file is actually has a e_machine of EM_MIPS.

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.
Fixes: #22308
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`.
Use the same `cmLinkLineComputer` subclass as the generator does. This
affects the base directory from which relative paths are computed.
