[sanitizer] Fix partially initialized static TLS range (#108685) 
Fixes asan, msan crash on check added in #108684.
The #108684 includes reproducer of the issue.

Change interface of `GetThreadStackAndTls` to

SizeClassAllocator64LocalCache::Init().

a5b06ad39a Partially revert "[NFC][msan] Split ThreadStart and Init" 
I don't know if removing "if (!start_routine_)" from ThreadStart
is NFC.

This reverts commit b3267bb3afd3c70a415ae81c855462affae92f6b.

1d3ef5f122 [MSAN] Add fiber switching APIs 
Add functions exposed via the MSAN interface to enable MSAN within
binaries that perform manual stack switching (e.g. through using fibers
or coroutines).

This functionality is analogous to the fiber APIs available for ASAN and TSAN.

Fixes google/sanitizers#1232
