[llvm-branch-commits] [sanitizer] Allow to override GetDTLSRange (PR #108348)

[Vitaly Buka via llvm-branch-commits]

https://github.com/vitalybuka created https://github.com/llvm/llvm-project/pull/108348

And rename it into __sanitizer_get_dtls_size.

The test will be in a separate patch, as I
expected reverts of the test.
