CMake: Fix undefined symbol: qt_resourceFeatureZstd issue

When cross-compiling, host rcc might generate zstd compressed
resources, even though the target might not support zstd
decompression.

To avoid that, we made sure to disable zstd compression when using
cmake api like qt_add_resources if the target platform does not
support it.
We did not do it for CMAKE_AUTORCC though.

In such a situation, the linker would fail with:
 error: undefined symbol: qt_resourceFeatureZstd

Add the --no-zstd option to AUTORCC_OPTIONS for targets that are
created by Qt CMake public API like qt_add_executable and
qt_add_library if the target platform does not support zstd
decompression (check via the QT_FEATURE_zstd variable).

This in turn applies to our own qt_internal_add_ API as well.

Allow opting out via the QT_NO_AUTORCC_ZSTD CMake variable.

[ChangeLog][Build System] Targets created with qt_add_executable
and qt_add_library will now add the --no-zstd option to AUTORCC_OPTIONS
when the target platform does not support zstd decompression. You can
opt out via the QT_NO_AUTORCC_ZSTD cmake variable.
