Fix gfx related shadowing warnings in blink/platform

A long term plan is to support -Wshadow in the code, which both might avoid
coding mistakes and reduce the risk of jumbo-specific build problems. This
fixes about half the shadowing problems in blink/platform, the half
that is related to gfx.

Bug: 925310

Explicit warnings this patch fixes:
