Introduce win32_target_ops::decr_pc_after_break

This adds a decr_pc_after_break member to win32_target_ops and updates
the two Windows targets to set it.

Note that I can't test the win32-arm-low.c change.

2019-11-26  Tom Tromey  <tromey@adacore.com>

	* win32-low.h (struct win32_target_ops) <decr_pc_after_break>: New
	field.
	* win32-i386-low.c (the_low_target): Update.
	* win32-arm-low.c (the_low_target): Update.
