wxTLS_PTR should have type of "T*" instead of being simply usable as "T*"
because of its overloaded operator->(), otherwise the code relying on it being
"T*" and compiling without problems in wxHAS_COMPILER_TLS case could fail to
compile without compiler TLS support.
Closes#13644.

__thread keyword doesn't work correctly with at least some MinGW builds and in
particular TLS unit tests failed with the official 4.4 version.
Disable the use of __thread with MinGW entirely for now to be sure that the
generated code behaves correctly. In the future we should white list the known
good versions of MinGW and/or use run-time test for __thread support in
configure instead of compile-time one only.

Win32 API doesn't provide pthreads-like destructors, so we need to
emulate them to free per-thread allocated memory.
