The target property `ISPC_HEADER_SUFFIX` and associated global
variable now can control the suffix used when generating the
C/C++ interoperability ISPC headers.
In addition the default suffix is now "_ispc.h" which matches the
common convention that the ISPC compiler team uses and recommends.

Move rejection of `#`, `<`, and `>` characters in outputs and byproducts
to a generate-time check. This removes the front-end check that
disallowed generator expressions. The generators have already been
updated to handle them.
Fixes: #12877
Add test cases verifying that `CMAKE_APPLE_SILICON_PROCESSOR` set as
either a cache or environment variable causes that to be selected as the
host architecture. Also verify that sources compile using whatever is
selected as the host architecture, even when the explicit setting is not
used.

1. COMMAND_ERROR_IS_FATAL ANY will capture errors if the exit code is
non zero, there is a timeout or an abnormal exit.
2. COMMAND_ERROR_IS_FATAL LAST
will capture if only the last process has an exit code non zero, there
is a timeout or an abnormal exit.

48aac247e9 Compile with explicit language flag when source LANGUAGE property is set
2e67a75acd Embarcadero: Simplify addition of -P flag for C++

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.
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This change was originally made by commit 74b1c9fc8e (Explicitly specify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`.
