cross-unwinding can pass exception across runtimes e.g.
Multi-language applications ( nodejs native modules, python C extensions )
However, cross-unwinding is not default in libcxx for sometime [1]
it requires special handling at runtime by apps who use it
Switch recipe defaults to upstream defaults, which is to turn it off
This means native unwinding ( with in same runtime )
is build by default which is the most common case.
This also fixes libcxx/libunwind build errors
when enabling TC_CXX_RUNTIME = "llvm" on aarch64 particularly

'cross' dependencies are hard, the code currently handles adding MLPREFIX
in these cases but may not in future depending upon implementation.
Add the correct value explictly.

None of these recipes need a native build of Python as they don't depend
on native Python modules, nor build Python modules against the target.

Provide libunwind based on TC_CXX_RUNTIME
When TC_CXX_RUNTIME is set to be 'llvm' distro wants
to use llvm provided runtime elements therefore provide
libunwind when TC_CXX_RUNTIME = "llvm"

compiler-rt configure calls for c++ compiler which can cause C++ runtime to
not be detected on some Yocto autobuilder workers running ubuntu 24.04
therefore let it use gcc for native version
Set TOOLCHAIN_NATIVE for using clang for libcxx

-stdlib is needed in both cxxflags and ldflags since c++ compiler
will use these to chose the right c++ headers and libraries during link
-rtlib and -unwindlib are only needed during linking
Use LLVM_HOST_TRIPLE during cross compiling compiler-rt for target
this is used by cmake to compute target and compiler triples
Fix LLVM_RUNTIME_TARGETS to use HOST_ARCH, it does not need cross
compile triple which HOST_SYS is passing here

We are using clang-native to build the native versions of these recipes
but we are missing the needed compiler flags to let it c/c++ runtime
appropriately. This also ensures that meta-clang does not have to worry
about the compiler settings for nativesdk/native pieces separately.

This can ensure that meta-clang does not carry them and can rely on core layer
while mesa can use them too.
