[OpenMP] Use TLS for gtid on Solaris (#138508)
When running the `openmp` testsuite on Solaris/amd64, many tests `FAIL`
like
```
# | OMP: Error #11: Stack overflow detected for OpenMP thread #1
```
In a `Debug` build, I also get
```
# | Assertion failure at kmp_runtime.cpp(203): __kmp_gtid_get_specific() < 0 || __kmp_gtid_get_specific() == i.
```
Further investigation shows that just setting `__kmp_gtid_mode` to 3
massively reduces the number of failures.
Tested on `amd64-pc-solaris2.11` and `x86_64-pc-linux-gnu`.
