Revert "[dev][cpu-trace] Move private zircon/garnet headers to zircon-internal"

This reverts commit 937a00818b643d6222d873b6afd64f3382800f00.

Reason for revert: Finishing the hard transition in garnet would require bringing in an unrelated patch.

- clarify counters are really events
- be less verbose in referring to MCHBAR
- make sure ipm_get_properties fills in the entire result struct

[dev][cpu-trace] Replace use of the term "counter" with "event"

The term "event" is more generic and includes things that are not
counters (e.g., voltage, temperature).

[dev][cpu-trace] Add sampling rates 100,500

These rates don't make any sense when sampling retired instructions
or clock cycles. But they can be useful for less frequent events
to get more fidelity.

[dev][cpu-trace] Split out pc from sample trace records

Only include pc data in trace output if requested.
Include cr3 in trace output for associating record with a process.
Processor Trace does this, and this can then use the same reader
for providing symbolic access to an entire system.

[dev][cpu-trace] Remove unnecessary buffer start/end offsets

The start offset is only ever reasonably zero,
and the end offset we can get from the vmo size.

[dev][cpu-trace] Move public headers to zircon/device/cpu-trace

There will be more files describing cpu events and such,
and putting them all in zircon/device will reduce the S/N
ratio of the files there.

[device][intel-pm] more sample frequencies, split fixed counters up

Until we have the ability to set arbitrary sample rates, it's help to
have a bit more flexibility.
The fixed counters can take up a lot of space in the trace buffer,
but they are useful: Allow specifying a subset of them.
