gas: sframe: fix PR gas/33277

In SFrame stack trace format, the representation of stack offsets allows
for either 1-byte, 2-byte or 4-byte integers.

Add new internal function sframe_fre_stack_offset_bound_p () which
checks if the given offset is within bounds (at most as a 4-byte
integer).  Use this to check if CFA offset is within bounds, if not skip
emitting the FDE, and warn the user.
