gdb: introduce 'all_non_exited_process_targets' and 'switch_to_target_no_thread'

Browse Source 
Introduce two new convenience functions:

1. all_non_exited_process_targets: returns a collection of all process
stratum targets that have non-exited inferiors on them.  Useful for
iterating targets.

2. switch_to_target_no_thread: switch the context to the first
inferior of the given target, and to no selected thread.
