1694840 - Use pooled staging textures for RenderCompositorD3D11SWGL uploads

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, task)

Description

[Matt Woodrow (:mattwoodrow)]

We still see texture upload in profiles, like in bug 1692589.

Let's switch the default upload method to Upload_StagingPooled (using staging textures, and avoiding blocking on them becoming available with a pool of spares), since it has been faster in all tests thus far.
