OvmfPkg/PciHotPlugInitDxe: add helper functions for setting up paddings

Extract the SetIoPadding() and SetMmioPadding() functions, so that we can
set EFI_ACPI_ADDRESS_SPACE_DESCRIPTOR fields using parameter names and
values that are more friendly than the original field names and their
expected values.

Introduce the HighBitSetRoundUp32() and HighBitSetRoundUp64() functions
for calculating the last parameter ("SizeExponent") of SetIoPadding() and
SetMmioPadding().

Put the new functions to use when requesting the default reservations. (In
order to be consistent with a later patch, "SizeExponent" is calculated
for SetIoPadding() with HighBitSetRoundUp64().)
