MdeModulePkg/XhciDxe: Add PCD for the delay of HCRST

Browse Source 
https://bugzilla.tianocore.org/show_bug.cgi?id=4727

Recently some of XHCI host controllers require to have
extra 1ms delay before accessing any MMIO register
during reset. PHY transition from P3 to P0 can take
around 1.3ms and the xHCI reset can take around 1.5ms.
Add PCD to control the delay, the default is 2 ms.
