feature: support explicit memory locking

Browse Source 
Added lockMemory in context to explicitly locking memory,
Added a boolean flag in graphics_allocation to indicate the allocation
is locked, and modified memory_operations_handler to add lock().
Change the logic to work correctly with makeResident() when lock() is
called previously for the same memory region
