arch: kernel: lib: toolchain: Standardize TLS keyword

Browse source 
Up until now, the `__thread` keyword has been used for declaring
variables as Thread local storage. However, `__thread` is a GNU
specific keyword which thus limits compatibility with other
toolchains (for instance IAR).

This PR intoduces a new macro `Z_THREAD_LOCAL` which expands to the
corresponding C11, C23 or C++11 standard keyword based on the standard
that is specified during compilation, else it uses the old `__thread`
keyword.
