texture_cache: delete images without walking every channel's tables
Deleting an image stamped every entry of every channel's view-id map
with CORRUPT_ID (validation, which is on in release builds) and cleared
every channel's descriptor table bitmaps on the spot. On Mario Kart
World's title screen (~5,400 entries in 5 channels) that took 362 us
per deleted image, with dozens deleted a frame while the collector runs:
~10% of the time in its frames over 100 ms.
The stamp is debug-only now. The tables are invalidated along with it,
so every entry is written again before it is read. Invalidate() marks a
table and its bitmap is cleared on the next read, once however many
images were deleted in between. Same title screen: 3.7 us per deleted
image.
