What does this PR do?
This PR imports an upstream fix to
rb_profile_frames
from ruby/ruby#9310 into our own custom copy of that function.Motivation:
As explained in the comment, the situation being handled does not yet happen with dd-trace-rb in practice since we don't support profiling with MN threads enabled, but since we want to try supporting it at some point, I've gone ahead and imported the fix.

How to test the change?
