When `CMAKE_OSX_ARCHITECTURES` is not specified, we add the Xcode
setting `ONLY_ACTIVE_ARCH = YES` with the intention of targeting the
native architecture of the host. However, the default `ARCHS` value
chosen by "Xcode 12 Universal Apps" includes multiple architectures.
Add an explicit `ARCHS` setting with value `$(NATIVE_ARCH_ACTUAL)`
to tell Xcode to use the host's native architecture only.

A user could specify the same directory scope to set_property()
multiple times, which in conjunction with APPEND would append the
property multiple times.
Make sure to deduplicate scopes across both DIRECTORY and
TARGET_DIRECTORY options, so that a property is only appended
once in such a scenario.

Starting on macOS 11, the dynamic loader has a builtin cache of
system-provided dylib files. They do not actually exist on the
filesystem. However, runtime dependencies recorded in Mach-O binaries
can still have `LC_LOAD_DYLIB` entries referring to such dylib files by
absolute path. The dynamic loader simply resolves the paths from its
cache. Teach `file(GET_RUNTIME_DEPENDENCIES)` to skip dependencies on
such dylib paths. For practical software distribution purposes they do
not exist, or at least can be assumed available on all deployments.

Allow to specify both DIRECTORY and TARGET_DIRECTORY at the same time in
`set_source_files_properties()` and `set_property(SOURCE)` commands.
Add test cases and update the documentation.

The path to the 32 bit libraries in the Intel windows/redist folder use
ia32. I don't remember if this has changed at some point, but ia32 has
been used at least since Intel Fortran XE 2018.
The version is determined in two steps. First, the "spec date" is
detected and cached. Second, the date is converted to a version.
Move the second step out of the spec date cache guard condition
so that it runs every time even if the spec date is already cached.

Since commit dd378258f1 (FindJava: Do not accept OS X stub 'java' as
Java, 2014-10-24, v3.1.0-rc3~29^2) we try to avoid using the macOS
`/usr/bin/java` stub if no underlying implementation of Java is actually
installed. However, the message that `/usr/bin/java` prints when there
is no Java available has changed since then. Update our check to also
look for the new message.
While at it, revise the way we suppress `Java_JAVA_EXECUTABLE`.
Previously we set its cache entry to `Java_JAVA_EXECUTABLE-NOTFOUND`,
but that would cause the same find-and-reject sequence to be followed
every time CMake runs in a build tree. Instead, use the approach from
commit 2c0db404d1 (FindSubversion: Do not accept macOS stub without
Xcode implementation, 2020-05-28, v3.18.0-rc1~67^2). Leave the cache
entry alone and just set a normal variable of the same name to hide it.
Clarify the order in which --resource-spec-file, RESOURCE_SPEC_FILE,
and CTEST_RESOURCE_SPEC_FILE are searched, and add tests to
enforce this.
Fixes: #20914
Fix code added by commit d7679f6427 (QCMakeCacheView: use non-deprecated
List and Set constructions, 2020-06-10, v3.18.0-rc2~13^2), used
conditionally on Qt 5.14 or above, to compile as C++14.
Previously, `cm::static_reference_cast` used `invoke_result_t` and took
the address of `O::get`. This is not in complete conformance with
standard.
Change the implementation to use `std::declval<O>.get()` which is always
well-defined.
