This generator expression is the inverse of `LINK_ONLY` and only coveys
usage requirements for the purposes of compilation. Its intended use is
to avoid needing to export targets that do not have link usage
requirements (e.g., header-only libraries) when used by another target.

`AUTOGEN_USE_SYSTEM_INCLUDE` was added. `AUTOGEN_USE_SYSTEM_INCLUDE`
is a boolean property that can be set on a target to indicate that the
autogen target include directory should be added as a system include
directory or normal include directory to the target.
`nvcc --options-file` does not parse unquoted arguments in a response
file correctly if they contain `[]`. Quote the `--generate-code=` flags
we add for CUDA architectures.

Since commit b6c60f14b6 (macOS: Default to arm64 architecture on Apple
Silicon hosts, 2020-09-28, v3.19.0-rc1~63^2) we add `-arch arm64` by
default on Apple Silicon hosts if `CMAKE_OSX_ARCHITECTURES` is not set.
This is necessary to prevent the toolchain from selecting its own
default architecture based on that of the build tool (e.g., `x86_64`).
If `CMAKE_<LANG>_COMPILER_TARGET` is set, its `-target` flag tells the
compiler what architecture to use, so do not add `-arch arm64`.
Fixes: #24599
If a source file is not found, the error message reports a backtrace.
Previously the backtrace pointed at where the target was created.
In the case of `target_sources`, the missing source may have been
named elsewhere.
Fixes: #24538
It is a normal target, but will end up copying its internals from
another target. Keep track of this state so that such copying can only
occur when intended.
C++ modules are going to introduce a third concept of "synthesized"
targets, so update logic where needed to avoid assuming "not imported?
must be normal".
Also add an accessor method to perform queries against the visibility.
`INTERFACE` targets with C++ modules are basically BMI-only modules. It
is unknown if they will be useful directly (due to ODR of the `module
M;` initializers needing to live in some specific object file). However,
they will be used to attach BMI-only compilations of `IMPORTED` C++
modules.
Since commit f69d1872db (cmGeneratorTarget: Add caches to some
functions, 2022-11-23) we cache the computed link options for a target.
Cache the host and device link options separately.
Add caches to the following cmGeneratorTarget functions in order to
improve performance:
- GetIncludeDirectories
- GetCompileOptions
- GetCompileDefinitions
- GetPrecompileHeaders
- GetLinkOptions
- GetLinkDirectories
