The semantics of the `GENERATED` property do not depend on the kind of
target to which the sources are attached. Convert the tests to use
custom targets instead of executables so that we do not have to enable
the CXX language and initialize support of its toolchain for every case.
This significantly reduces the time the test takes to run.
When cross-compiling with Xcode our compiler id test binary may be
compiled with multiple architectures. The INFO strings should be
identical and therefore de-duplicated. However, this can be broken by
stray text that happens to sit immediately before or after an INFO
string. Filter out such text so we can match clean INFO strings.
Fixes: #21526
Update logic added by commit 6051a49c78 (Visual Studio: Add Android
support, 2020-06-12, v3.19.0-rc1~619^2) to only look for VS
installations using `cmake_host_system_information` on Windows hosts.
Otherwise the `VS_*_DIR` keys are not available.
Fixes: #21547

This change was originally made by commit 74b1c9fc8e (Explicitly specify
language flag when source LANGUAGE property is set, 2020-06-01,
v3.19.0-rc1~722^2), but it was reverted by commit 30aa715fac (Revert
"specify language flag when source LANGUAGE property is set",
2020-11-19) to restore compatibility with pre-3.19 behavior.
Implement the change again, but add policy CMP0119 to make this change
while preserving compatibility with existing projects.
Note that the `Compiler/{Clang,Intel,MSVC}-CXX` modules do not need to
specify `-TP` for their MSVC-like variants because we already use the
flag in `CMAKE_CXX_COMPILE_OBJECT`. Similarly for `Compiler/XL-CXX`
and `Platform/Windows-Embarcadero`.
Note also that this does not seem possible to implement for XL C.
Even with `-qsourcetype=c`, `xlc` complains about an unknown suffix:
`1501-218 (W) file /.../AltExtC.zzz contains an incorrect file suffix`.
It returns non-zero even with `-qsuppress=1501-218`.
