freedreno: add a7xx perfcounter support

Add performance counting support for a7xx in Freedreno, providing the
available performance counter groups along with the lists of countables
that can be counted through related counters.

All the collected countable names and values are provided in enum
definitions, even when the names indicate some countables being reserved.
The perfcounter groups don't include those reserved values.

The countable selection command stream in fdperf is enabled for a7xx,
sharing the same command stream created for 5th- and 6th-gen devices.
