Xcode 12 doesn't allow nested builds within the same build directory.
That means we can no longer do an install by building the install target
when IOS_INSTALL_COMBINED is true. We can, however, still do an install
by running the cmake_install.cmake script or executing cmake --install,
since there is no outer build and therefore the associated SDK can be
built as a sub-build.
The non-build methods previously didn't work when
IOS_INSTALL_COMBINED was true because the generated install script
and the CMakeIOSInstallCombined script both made certain assumptions
that relied on being part of a build. Those assumptions are now
removed. A side-effect of this work is that cpack now also works from the
command line when IOS_INSTALL_COMBINED is true.

Starting with Clang 12, `otool -l` reports `LC_LOAD_WEAK_DYLIB` instead
of `LC_LOAD_DYLIB` for weakly linked libraries. Update the
implementation of `file(GET_RUNTIME_DEPENDENCIES)` to recognize these.

The Xcode "new build system" only considers a script build phase up to
date if it has run before, even if outputs are newer than inputs. Use a
deterministic object id for script build phases associated with custom
commands so that they do not need to re-run after CMake re-generates the
project.

The test requires a non-empty `CMAKE_BUILD_TYPE` to function on
single-config generators. Force a non-empty configuration if the test
is configured explicitly with empty `-DCMAKE_BUILD_TYPE=`.
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.
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.

Revert commit 74b1c9fc8e (Explicitly specify language flag when source
LANGUAGE property is set, 2020-06-01, v3.19.0-rc1~722^2) and the lookup
tables from its two immediate ancestors. The purpose of that change was
to convert an explicit `LANGUAGE` source file property into an explicit
language specification compiler flag like `-x c`. This seems reasonable
since the property is documented as meaning "indicate what programming
language the source file is". It is also needed to help compilers deal
with non-standard source file extensions they don't recognize.
However, some projects have been setting `LANGUAGE C` on `.S` assembler
source files to mean "use the C compiler". Passing `-x c` for them
breaks the build because the `.S` sources are not written in C. These
projects should be updated to use `enable_language(ASM)`, for which
CMake often chooses the C compiler as the assembler when using
toolchains that support it (which would have to be the case for projects
using the approach).
Revert the change for now to preserve the old behavior for such projects.
We can re-introduce it with a policy in a future version of CMake.

The old `check_X_source_runs` modules did not verify the arguments, so
we cannot start doing it now. Downgrade the hard error introduced in
commit 357e2ef429 (CheckSoureRuns: Add a unified way to check if a
source runs, 2020-09-14) via !5223 into a noisy warning.
In the following scenario (with 3.18 policies):
1. A CXX target is created.
2. CUDA language is enabled.
CMake 3.18 introduced CMP0104, which requires CUDA_ARCHITECTURES to be
set. Because the CXX target was created before CUDA was enabled it
wouldn't have it set. The Visual Studio generator would however end up
computing CUDA compile options for the CXX target, which would result in
a fatal error due to the policy violation.
There doesn't seem to be a reason to do this for targets that don't
actually use the CUDA language, so we can skip and generate the CXX
target just fine.
Fixes: #21341
