ArmPkg: remove DebugUncachedMemoryAllocationLib
The debug implementation of the UncachedMemoryAllocationLib library class relies on the creation of an uncached alias of a memory range, while keeping the original cached mapping, but with read-only attributes to trap inadvertent write accesses. This is not a terribly good idea, given that the ARM architecture does not allow mismatched attributes, and so creating them deliberately is not something we should encourage by doing it in reference code. So remove the library, and replace all references to it with a reference to the non-debug version (unless the platform does not require a resolution for it in the first place, in which case all UncachedMemoryAllocationLib references can be removed altogether).

-/** @file
- Debug version of the UncachedMemoryAllocation lib that uses the VirtualUncachedPages
- protocol, produced by the DXE CPU driver, to produce debuggable uncached memory buffers.
-
- The DMA rules for EFI contain the concept of a PCI (DMA master) address for memory and
- a CPU (C code) address for the memory buffer that don't have to be the same. There seem to
- be common errors out there with folks mixing up the two addresses. This library causes
- the PCI (DMA master) address to not be mapped into system memory so if the CPU (C code)
- uses the wrong pointer it will generate a page fault. The CPU (C code) version of the buffer
- has a virtual address that does not match the physical address. The virtual address has
- PcdArmUncachedMemoryMask ored into the physical address.
