MdeModulePkg/NvmExpressPei: Use BaseLib for 64-bit multiplication
In NvmeCreatePrpList(), calculating the PRP entry offset via
`PrpEntryIndex * sizeof (UINT64)` uses 64-bit multiplication since
PrpEntryIndex is UINT64. On 32-bit architectures (IA32), 64-bit
multiplication must use BaseLib math functions.
Use MultU64x32() for the 64-bit offset calculation and add BaseLib
to the module INF and header.

MdeModulePkg/NvmExpressDxe: Use BaseLib for 64-bit multiplication
Commit bf0dc7d78701 ("MdeModulePkg: Fix comparison with wider widths")
changed PrpListIndex and PrpEntryIndex from UINTN to UINT64. In
NvmeCreatePrpList(), performing arithmetic with `PrpListIndex * EFI_PAGE_SIZE`
and pointer indexing with `(UINT64 *)PrpListBase + PrpEntryIndex` results
in 64-bit multiplication.
Fix this issue by using MultU64x32() for 64-bit page offset calculations
and casting PrpEntryIndex to UINTN for pointer indexing.
