external: update pdfium to 4021

(cherry picked from commit 1cb70721ba00dd6c6958f0a10e39aa5c1866ec96)

This is the commit message #2:

external/pdfium: C++20 comparison operator fix

Missing const leads to overload resolution ambiguity when a synthesized
candidate of operator == for a reversed-argument rewrite conflicts with the
actual operator ==, due to the asymmetric const-ness of the implicit object
parameter and the RHS parameter:

(cherry picked from commit 6e0461d576d9f386e458f98f3c57f0ba385aacb4)

This is the commit message #3:

pdfium: don't patch out the COMPONENT_BUILD check, define it

So next time we update, no need to adapt a failing patch.

(cherry picked from commit 9b4ab9bda41a818832c721933986c9c6e07a6e6c)

This is the commit message #4:

make update_pch also consider files in <module>/src/**/inc

With --enable-pch=full there's not much difference between a "public"
header in <module>/inc and a private one in <module>/src/somewhere/inc .
And since the script searches recursively, this apparently helps to
find even more headers for lower pch levels.

[ Just the pdfium part. ]
