[Cherry-pick] Make sure the correct ANGLE binary is used.

Previously when eglGetDisplay is called, the code would attempt to
initialize ANGLE platform methods and acquire pointers to reset the
ANGLE platform. However, without this patch we continue using
ro.hardware.egl to form the ANGLE binary name, which is now wrong. Not
being able to correctly load the ANGLE binaries means platform methods
are not initialize. This currently doesn't have known side effect except
that we are observing a bunch of error messages that don't make sense
that point to the native OpenGL ES driver loading failure. This patch
makes sure ANGLE binary is used when initialize ANGLE platform.
