Peter Zhu 96d57e2403 Make rb_str_no_gvl_safe_acquire public C API ...

This commit renames rb_str_tmp_frozen_no_embed_acquire to rb_str_no_gvl_safe_acquire
and makes it part of the public C API.

There is currently no way for C extensions that use no GVL operations to
safely read from a string because it has no way of guaranteeing that the
string is not embedded. Embedded strings are not safe for no GVL operations
because GC compaction can run, which will mprotect the memory region and
will cause any read to SEGV.

See https://github.com/ruby/ruby/pull/9817 for when rb_str_tmp_frozen_no_embed_acquire
was introduced.
