Support *-srgb format as dst formats in CopyTextureForBrowser

Dawn allows texture-to-texture copy happens between the textures that
formats only have diff on srgb-ness.

CopyTextureForBrowser could align on this rule to achieve copying to
*-srgb dst texture and keep the bytes the same as copying to non-srgb
formats.

This CL add support for *-srgb textures as dst textures and using an
extra gamma decoding step for this.
