gpu: Disable Mali Vulkan protected memory

Browse source 
To support L1 HWDRM, Mali DDK now builds with protected memory feature
enabled on some platforms e.g. Geralt, but we are not ready to advertise
this feature to the guest side on those platforms.

Add an environment variable to disable the feature at runtime.

BUG=b:339766043
TEST=CtsDeqpTestCases dEQP-VK.protected_memory.* pass
