chore: bump chromium to 129.0.6650.0 (main) (#43266)

* chore: bump chromium in DEPS to 129.0.6645.0

* chore: update patches

* chore: bump chromium in DEPS to 129.0.6646.0

* refactor: remove ppapi dependency

PPAPI removal - https://issues.chromium.org/issues/40511450
PDF viewer migration - https://issues.chromium.org/issues/40511452

* chore: update patches

* chore: enable `content_enable_legacy_ipc`

We were indirectly relying on this via `enable_ppapi=true`, with
633a57d9b62da7850ef7946f6b101ed440d04cdd ppapi is now disabled and
this commit makes the dependency explicit.

* fix: gn check
