Alex Gough fe35cd43f2 Allow breakpad to read extended amd64 contexts ...

Minidumps can contain extended, and compacted extended, contexts to
include xstate data such as the state of the cet registers cetumsr
and cetussp. Previously breakpad would reject dumps with contexts
larger than expected. With this chage, breakpad now accepts and reads
these minidumps. This change does not yet add processing for this
extra data, but will allow any minidumps to be passed on to other
processing tools, or be available for manual inspection.

See chromium-review.googlesource.com/c/crashpad/crashpad/+/2575920
for motivation.
