1572843 - Fix WR texture cache upload when using no swizzling

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, defect)

Description

[Dzmitry Malyshau [:kvark]]

External images (e.g. video frames) are shown as swizzled when running on a Mac that doesn't support swizzling (see bug 1570736).

This is a medium-size follow-up to D21965.

Refactors the use of swizzling by the texture cache. Adds a device
capability flag that is checked at run-time. Also makes the texture
cache to communicate with the texture uploader if there is a format
conversion needed, which fixes the case on platforms that don't
support swizzling.
