ArmVirtPkg: handle virtual EL2 timer in DT

FEAT_VHE, introduced in ARMv8.1, adds a virtual EL2 timer.
However, this library verifies that exactly 3 or 4 12-byte timer
interrupts are provided in input DT, ASSERTing when the new timer
is added.

Change the assert to >= 36.

Extend the current logic, also initializing PcdArmArchTimerHypVirtIntrNum
if 5 interrupts are provided.
