[sanitizer] Add CHECK that static TLS info is ready (#108684)
There is possibility of
static_tls_begin is set and static_tls_end is not yet
The test reproduces the case.
Stack trace looks like this:
* `MsanThread::Init`
* `SetThreadStackAndTls`
* `GetThreadStackAndTls`
* `GetThreadStackTopAndBottom`
* `pthread_getattr_np`
* `realloc`
* `__sanitizer_malloc_hook`
* TLS access
* `___interceptor___tls_get_addr`
* `DTLS_on_tls_get_addr`
The issue is that `SetThreadStackAndTls` implementation
stores `tls_begin` before `GetThreadStackTopAndBottom`,
and `tls_end` after. So we have partially initialized
state in `DTLS_on_tls_get_addr`.
