qmuntal 715d53c090 runtime: fallback to TEB arbitrary pointer when TLS slots are full
The Go runtime allocates the TLS slot in the TEB TLS slots instead of
using the TEB arbitrary pointer. See CL 431775 for more context.

The problem is that the TEB TLS slots array only has capacity for 64
indices, allocating more requires some complex logic that we don't
support yet.

Although the Go runtime only allocates one index, a Go DLL can be
loaded in a process with more than 64 TLS slots allocated,
in which case it abort.

This CL avoids aborting by falling back to the older behavior, that
is to use the TEB arbitrary pointer.

Fixes #59213
