c4941b7e66 ARMClang: Do not automatically add cpu/arch compile or link options

The compile options `--march=<arch>` and `--mcpu=<cpu>` and the
link option `--cpu=<cpu>` are automatically added by CMake based
on `CMAKE_SYSTEM_PROCESSOR` or `CMAKE_SYSTEM_ARCH`. But this is not
sufficient, because armclang also supports enabling or disabling
features using `+<feature>`:
-mcpu=<name>[+[no]<feature>+...]
For example:
-mcpu=cortex-a57+nocrypto+nofp+nosimd+crc
(Reference: https://developer.arm.com/documentation/dui0774/k/Compiler-Command-line-Options/-mcpu?lang=en)
The problem is, even if a project adds a flag with features it needs,
CMake still adds flags, resulting in code that is compiled with wrong
CPU features and unable to run.
Add policy `CMP0123` to not automatically add compile or link options,
and let projects set them instead.

Since commit da7ad7997e (WriteCompilerDetectionHeader: Add policy to
remove module, 2020-12-04, v3.20.0-rc1~350^2), the WCDH module is
deprecated. Update the `cmake-compile-features(7)` manual section that
previously recommended WCDH to make such detection the project's
responsibility instead. Move the old content of the section over to the
WCDH module to preserve it.
The placement of the word "optionally" implied that the fields mentioned
before are not optional, which is not the case starting from version 3
of the presets.
In v3 of the presets, generator and buildDir can be omitted to fall
back to regular cmake behavior when these values are not explicitly
provided by the user.

Define `PROJECT_IS_TOP_LEVEL` and `<PROJECT-NAME>_IS_TOP_LEVEL`. The
latter is a STATIC cache entry just like other `<PROJECT-NAME>_*`
variables so that it is globally scoped.
