[PATCH 2/5] gdb: add inferior parameter to set_target_gdbarch, rename to set_inferior_gdbarch

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

From: Simon Marchi <simon.marchi@polymtl.ca>

Add an inferior parameter, so it doesn't depend on the current
inferior.  While at it, rename to set_inferior_gdbarch, I think that's a
better name than "target".

The sole observer of the architecture_changed observable,
pyuw_on_new_gdbarch, doesn't seem to depend on the current inferior.
Neither does registers_changed.

Update callers to pass the current inferior, no change in behavior is
expected.
