anv: Bump VkDeviceMemory objects limit to 4GB

Android CTS 13_r4 tests dEQP-VK.memory.allocation.random* fail
with VK_ERROR_OUT_OF_DEVICE_MEMORY on ADL boards with 32GB memory
as memory allocation requests from DEQP are much larger(~2.9GB+)
based on device heap size/8.

Increase the limit to unsigned 32bit max(~4GB) which helps to
fix the dEQP-VK.memory.allocation.random* tests.

v1: Bound allocation by the largest memory heap size (Lionel Landwerlin)

v2: Clean up comments to reflect the code change (Ivan Briano)
    Update the value of MAX_MEMORY_ALLOCATION_SIZE (Lionel Landwerlin)
