ArmVirtPkg/MemoryInitPei: Remove Non-RT Types from Mem Type Info HOB

Removes the following types from the memory type information HOBs
produced in the MemoryInitPei PEIM:

- `EfiBootServicesCode`
- `EfiBootServicesData`
- `EfiLoaderCode`
- `EfiLoaderData`

Our platform has a memory type information validation routine that
currently expects those types to be excluded as they would not impact
the UEFI memory map since they are not runtime memory types.

This follows the guidance in the whitepaper "A Tour Beyond BIOS
Memory Map and Practices in UEFI BIOS".

https://github.com/tianocore-docs/Docs/raw/master/White_Papers/A_Tour_Beyond_BIOS_Memory_Map_And_Practices_in_UEFI_BIOS_V2.pdf

"NOTE: We recommend a platform only define the ReservedMemory,
ACPINvs, ACPIReclaim,  RuntimeCode, RuntimeData in Memory Type
Information table, because OSes only request  these regions to be
consistent. There is no need to add BootServicesCode,
BootServicesData, LoaderCode, LoaderData in memory type information
table, because these regions will not be reserved during S4 resume."

Since these memory types are not tracked in memory type information
any longer it also reduces the number of resets that may need to
occur to update memory type buckets that are not needed.
