Revert "Switched highp float to highfloat and mediump float to half."

This reverts commit 88d99c63878c2d3d340120f0321676f72afcb4f0.

Reason for revert: Believed to be causing unit test failures in Chrome roll:

https://build.chromium.org/p/tryserver.chromium.android/builders/linux_android_rel_ng/builds/364433
https://luci-logdog.appspot.com/v/?s=chromium%2Fbb%2Ftryserver.chromium.android%2Flinux_android_rel_ng%2F364433%2F%2B%2Frecipes%2Fsteps%2Fcontent_browsertests__with_patch__on_Android%2F0%2Flogs%2FWebRtcCaptureFromElementBrowserTest.VerifyCanvasWebGLCaptureColor%2F0

Original change's description:
> Switched highp float to highfloat and mediump float to half.
> 
> The ultimate goal is to end up with "float" and "half", but this
> intermediate step uses "highfloat" so that it is clear if I missed a
> "float" somewhere. Once this lands, a subsequent CL will switch all
> "highfloats" back to "floats".
