Bryan Bernhart 650859b420 Use first-fit policy to reduce upload memory.
Reverts CL9160 by replacing the existing policy with one
that re-uses smaller ring-buffers.

No change for Vulkan. About 3x faster with D3D.

Jiawei Shao 49aae0f3bd Double the size of the ring buffer only when it is not big enough
Currently Dawn always doubles the size of the largest ring buffer
everytime when DynamicUploader::Allocate() is called, which is not
necessary and will cause out-of-memory errors when this function is
called for too many times. This time fixes this behaviour by only
doubling the size of the largest ring buffer when it is not big enough
for the request buffer size.

Austin Eng 233ce73c50 Add Create/ReleaseStagingBuffer to DynamicUploader
StagingBuffers need to be created and explicitly released outside of
the RingBuffer for CreateBufferMapped since the staging buffer must live
until the Buffer is Unmapped or Destroyed. This patch adds methods to the
DynamicUploaded for creating and tracking the release of StagingBuffers.

This patch also fixes SerialQueue for non-copy-constructible types.

Bryan Bernhart 67a73bd9fa Memory manager: buffer uploads (Metal+refactor) - Part 3
Manages a single persistently mapped GPU heap which is sub-allocated
inside of ring-buffer for uploads. To handle larger buffers without additional
unused heaps, ring buffers are created on-demand.
