WebGL2 & 16-bit depth capture: Upload video to GL_RED float texture.

WebGL2 & 16-bit depth capture: Upload video to GL_RED float texture.

This enables lossless access to 16-bit video stream using GL_RED float texture on WebGL2.

The patch extends the WebGL1 approach using RGBA32F textures for 16-bit depth video [*]
by using single component GL_RED float [**] texture on WebGL2.

* https://crrev.com/2476693002/
** Float is used for no-precision-loss access to 16-bit data normalized to
[0-1.0] range using formula value_float = value_16bit/65535.0.

Fair enough, I should know this by now :)

And,... probably shouldn't guess that someone is busy/OoO based on crbug and
review activity during two days.

android_n5x_swarming_rel just got removed from CQ.

Although experimental
(https://bugs.chromium.org/p/chromium/issues/detail?id=672382#c32)
CQ seems to be still running android_n5x_swarning_rel so I will probably restart
this later.
