pdfium: update to 3471

Allows dropping 4 API patches + the one that allows building against
system ICU.

(cherry picked from commit 1445d84cdc906fabf6cc7a59f3c94b4049477701)

Conflicts:
	external/pdfium/0002-svx-more-accurate-PDF-text-importing.patch.2
	external/pdfium/UnpackedTarball_pdfium.mk

[ Also split up edit.patch.1 which as done when forward-porting from
cp-6.0 to cp-6.2, so not something that could be backported explicitly. ]
