Move the logic for appending cubin afterwards, so the check can simply be
empty().
With the Makefile generator the option is now at the front instead of being
intermixed with the actual bins.
Currently, this feature is only supported on ELF platforms. So, the property
LINK_WHAT_YOU_USE will be ignored for other plateforms.
Moreover, flags and commands are now controled by CMake variables.

The `GetSourceFilePath` method is meant only for compiled sources, and
automatically handles converting it to a path for the Ninja build
manifest. Rename the method to clarify both.
If the shared object name contains spaces, they need to be properly
escaped, or link command will fail.
This was already done for soname symlink creation in commit 13c92b4a30
(Ninja: Fix creation of library symlinks in folders with spaces,
2019-05-20, v3.15.0-rc1~87^2).

For NVCC the compiler takes care of device linking when passed the "-dlink"
flag.
Clang doesn't support such magic and requires the buildsystem to do the work
that NVCC does behind the scenes.
The implementation is based on Bazel's device linking documentation:

In commit 99ed39b011 (Ninja Multi-Config: Make link response files
per-config, 2020-07-15, v3.17.4~3^2), we added the target directory to
the response file under the mistaken assumption that two different
targets with the same name could be in different directories. However,
this causes the path to the response file to be too long to fit on a
command line. Take the path back out, while leaving in the per-config
split.
Fixes: #21050
properties LINK_OPTIONS and INTERFACE_LINK_OPTIONS are propagated
to the device link step.
To control which options are selected for normal link and device link steps,
the $<DEVICE_LINK> and $<HOST_LINK> generator expressions can be used.
Fixes: #18265
Since commit d91b5a72cd (Ninja: Add support for CUDA nvcc response
files, 2019-05-30, v3.15.0-rc1~8^2) we use NVCC's `--options-file`
option to avoid long link command lines via a response file. However,
for non-device linking the host tools are used and the option does not
make sense. Update the logic to use `--options-file` only for device
linking. Linking with the host tools already has its own logic for
response files.
Fixes: #19954
This adds logic to properly handle Swift executables. Only executables
marked as exporting symbols will now generate module interfaces for the
executable.
Since commit 0f150b69d3 (AIX: Explicitly compute shared object exports
for both XL and GNU, 2019-07-11, v3.16.0-rc1~418^2~2) we always export
all symbols from shared libraries by default. Add a new target property
called `AIX_EXPORT_ALL_SYMBOLS` that can be explicitly set to OFF to
suppress this behavior and export no symbols by default.
Fixes: #20290
Many users will want to use the Ninja Multi-Config generator like a
traditional Visual Studio-style multi-config generator, which doesn't
mix configurations - custom commands are built using target executables
of the same configuration the command is for. We do not want to force
these people to generate an N*N build matrix when they only need N*1,
especially if they have lots of targets. Add a new variable,
CMAKE_NINJA_CROSS_CONFIG_ENABLE, to opt-in to the cross-config build
matrix.
