Revert "Remove PPAPI if NaCl is disabled"

This reverts commit 45c5328582baa317fe827f5c568047810bea3277.

Reason for revert: This CL seems to be the reason that causes some archive bots failures. There are three bot failures: https://ci.chromium.org/ui/p/chromium/builders/ci/mac-arm64-archive-rel, https://ci.chromium.org/p/chromium/builders/ci/mac-archive-rel and https://ci.chromium.org/p/chromium/builders/ci/linux-archive-rel. Both failed because missing blink_test_plugin and blink_deprecated_test_plugin, which seems to be part of ppapi. First failures on: https://ci.chromium.org/ui/b/8763785537596666865, https://ci.chromium.org/ui/b/8763784707698597681, and https://ci.chromium.org/ui/b/8763784745244932353
