arch, vmm: Fix TDVF section handling

Browse Source 
This patch fixes a few things to support TDVF correctly.

The HOB memory resources must contain EFI_RESOURCE_ATTRIBUTE_ENCRYPTED
attribute.

Any section with a base address within the already allocated guest RAM
must not be allocated.

The list of TD_HOB memory resources should contain both TempMem and
TdHob sections as well.
