libEGL: Add initialization tracing
The first call to eglGetDisplay() loads drivers and initializes
dispatch tables. This currently takes significant time (85-100 ms),
and can must be done before the first frame of an app can be shown.
This change adds systrace markers for the major parts of this process,
as a precursor to optimizing them.
Bug: 34404021
Test: manual systrace of calculator app startup on bullhead
