Here is a diff to add support for Indirect branch tracking (IBT) by
merging the needed patches for boringssl. It based on robert's diff:

https://github.com/openbsd/ports/commit/8485e4d8db4d9325cce4db61881648dfcfce5ef1


I tested with konqueror and 12th Gen Intel i7-1260P. Test cases: youtube and 
HTTPS.

Here are a few more changes:

The patch-src_buildtools_config_linking_pri patch was a stupid leftover
for the upgrade process.

+        QMAKE_LFLAGS += -Wl,-z,nobtcfi
+        QMAKE_LFLAGS += -Wl,-z,wxneeded

This had no effect. (pre check if macos|ios)

I also removed "content/browser/tracing/BUILD.gn" by pre-configure
instead of a patch to avoid an annoying "update-patches" massages.

Feedback, OK?
