patches: review pass 3 - move block_input to origin patches

Browse Source 
block_input protection moved from P0008 to their respective origin
patches for independent compilability (GNU Emacs requirement):
- P0001 (ns_ax_buffer_text): now has block_input + record_unwind
- P0003 (postCompletionAnnouncementForBuffer): now has block_input
- P0004 (ns_ax_scan_interactive_spans): now has block_input

P0008 now only adds its own new functionality (child frame completion
announcements, echo area announcements) without duplicating block_input
from earlier patches.

All 9 patches apply cleanly with git am on Linux git 2.43.0.
