ArmPkg/ArmV7Mmu: fix write-through translation table accesses
The definition TTBR_WRITE_THROUGH_NO_ALLOC makes little sense, since
a) its meaning is unclear in the context of TTBRx, since write through
always implies Read-Allocate and no Write-Allocate
b) its definition equals the definition of TTBR_WRITE_BACK_ALLOC
So instead, rename it to TTBR_WRITE_THROUGH and update the definition
to reflect the name.
