Move raster query queue to its own class

Previously, the raster query queue was part of the
GpuRasterBufferProvider. Soon, we plan to access that queue from
multiple locations. Not all of them are tied to the
GpuRasterBufferProvider.

This CL moves the raster query queue to its own class so it can be
cleanly accessed from other locations.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
