Refactor graphics memory allocation scheme

Browse Source 
- replace createGraphicsAllocationWithRequiredBitness with more general
methodallocateGraphicsMemoryInPreferredPool based on passed
 AllocationData
- proper flags for allocation selected based on AllocationType

- remove allocateGraphicsMemory(size_t size, size_t alignment)
and use allocateGraphicsMemory(size_t size) instead where default
alignment is sufficient, otherwise use full options version:
allocateGraphicsMemory(size_t size, size_t alignment,
 bool forcePin, bool uncacheable)
