Skip Gamma and Gamut conversions for BT.709->SRGB

Browse Source 
This introduces a new field 'doYuvToRgbConversionOnly' in
ExternalTextureParams to have the WGSL only do yuv->rgb conversion for
better performance. User studies shows that users don't really care
about the Gamma difference between 2.4 and 2.2.
