Revert "Vulkan: honor bufferImageGranularity the simplest way."

This reverts commit 48183b8f58a293d3eaf5f9eec72519bf60e5df85.

Reason for revert: Part of Dawn->Chromium breakage

BUG=dawn:950

Original change's description:
> 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.
