gdb: pass execing and following inferior to inferior_execd observers

Browse Source 
The upcoming patch to support exec in the amd-dbgapi target needs to
detach amd-dbgapi from the inferior doing the exec and attach amd-dbgapi
to the inferior continuing the execution.  They may or may not be the
same, depending on the `set follow-exec-mode` setting.  But even if they
are the same, we need to do the detach / attach dance.

With the current observable signature, the observers only receive the
inferior in which execution continues (the "following" inferior).

Change the signature to pass both inferiors, and update all existing
observers.
