Corentin Wallez 48183b8f58 Vulkan: honor bufferImageGranularity the simplest way.
Vulkan requires that linear and opaque resources be placed in different
"pages" of bufferImageGranularity size, as some hardware uses the page
table to contain some compression bits or other stuff. Make Dawn honor
this limit by aligning all allocations to bufferImageGranularity. This
is pretty bad and should be improved later.

Also does some cleanups:
 - Add kMappableBufferUsage to represent all mappable usages.
 - Remove the proxy function for resource management from
   vulkan::Device and call ResourceMemoryAllocator directly.
 - Use an enum to make the difference between mappable, linear and
   opaque resources.

This issue was found while doing a change of the memory type selection
in Vulkan, that started failing some unrelated tests on Nvidia. Without
knowing the details of the HW or the driver it is really hard to write
tests, except by copy-pasting a failing test. This is why there is no
test added in this CL, and instead will rely on tests not failing with
the follow-up CL.
