runtime: print stack of G during a signal
Sequence of operations:
- Go code does a systemstack call
- during the systemstack call, receive a signal
- signal requests a traceback of all goroutines
The orignal G is still marked as _Grunning, so the traceback code
refuses to print its stack.
Fix by allowing traceback of Gs whose caller is on the same M as G is.
G can't be modifying its stack if that is the case.
Fixes #10546
