[PATCH 4/5] gdb/amd-dbgapi: factor out require_forward_progress overload to target one inferior

[Simon Marchi <simon.marchi@efficios.com>]

A following patch will want to call require_forward_progress for a given
inferior.  Extract a new require_forward_progress overload from the
existing require_forward_progress function that targets a specific
inferior.
