libpmc: Explicitly whitelist json fields

Adds all missing Intel fields and turns jevents.c into an explicit white
list mechanism so that we no longer ignore important fields that often
invalidate the counter. The json event parser must now parse every
field on each architecture that we support. This has been tested by
running tinderbox and manually running jevent against our current json
repository. As a bonus I fixed spelling errors in the AMD JSON
definitions.

hwpmc: Fix PMC flags for AMD Zen cores

The PMC flags available for DF and L3 counters were not all implemented.
More importantly, the field encodings for the L3 counters changed in an
incompatible way between Family 17h and Family 19h. Similarly, the
field encodings for the DF coutners changed between Family 19h and 1Ah.
I also added the precise retire flag for the 3rd core counter.

Lastly, I added a warning in the jevent parser because ignoring the
unknown fields results in counters incorrectly programmed. We should
not just ignore that.
