net/bnxt/tf_ulp: tune performance for Thor2 stats cache

This change adds changes the act get API to expect a physical
address for the host memory rather than a pointer to a local
virtual address. The change was made because the virt->phys
API call has a very high overhead. Also included in this change
to the mutex locks and delays within the main loop.

net/bnxt/tf_ulp: fix F1F2 VXLAN counter accumulation

Add code for Thor2 to support the counter accumulation for
F1F2 vxlan parent-child flows.
Also, add a check for device state in the TF tunnel free API,
if it is zero then TF will skip the resource free as it
was already done by bnxt_free_all_hwrm_resources.

net/bnxt/tf_ulp: add stats cache for Thor2

This change adds a stats cache for Thor2 flows using counters.
Flow stats will be harvested periodically in the background
and stats reads by the application will be returned stats from
the cache and not by initiating a read from HW.

This change also adds read-clear functionality for counter resets
and restructures the stats collection while loop to
guarantee full coverage of entries added or removed during the
collection period.
