Deduplicate IsScaleAndIntegerTranslate

There are two identical implementations iof IsScaleAndIntegerTranslate() in
components/viz/service/display. One in skia_renderer.cc and one in
software_renderer.cc.

When building components/viz with jumbo (not yet on master) those end
up in the same translation unit and cause compilation errors.

This CL deduplicates the functions and puts it in a shared utility file,
renderer_utils.cc.

[jumbo] Merged two GetActiveTextureUnit functions

In jumbo build experiments, two (identical but small)
GetActiveTextureUnit() functions ended up in the same translation
unit which caused the compiler to fail.

This patch moves the useful function into a shared utility file.

This landed last Thursday but I failed to reference this bug.

The commit message is:

    Support jumbo builds in components/viz
    
    Jumbo is a unity build system for Chromium. By combining many cc files
    in the same translation unit, the compiler doesn't have to repeat all
    the work triggered by shared header. This normally makes building 5-20
    times faster.
    
    The downside to jumbo is that code intended to be local to one cc file
    suddenly becomes more exposed and might clash with other code.
    
    Jumbo support in components/viz currently saves about 5 CPU minutes of effort,
    about 1% of the total reference build effort.
