Hypervisor: L1TLB PLRU updated by sector hit mismatching Virtual bit

[ingallsj]

Related issue: after #2841

Type of change: other enhancement

Impact: no functional change

Development Phase: implementation

Release Notes
The sectorHit function in the TLB is used for PLRU updates and inserting new entries in the same sector.
The TLBEntry.hit function includes both vpn and virtual arguments to distinguish between HS/HU or VS/VU entries, but the sectorHit function does not. This won’t cause problems when inserting new entries in the same sector, but can allow misses due to mismatching Virtual bit to still update the PLRU as if they were a hit.

1. The fix is to add a virtual argument to the TLBEntry.sectorHit function.
2. A further optimization after the fix is to move the v bit from TLBEntryData to be a single tag bit alongside vpn.
