DXT1_RGBA and sRGB variants of DXT[135] formats are enabled as
valid format on V3D.

Once all S3TC formats supported by V3C are enabled the following
extensions become exposed by gallium.

    * GL_ANGLE_texture_compression_dxt3
    * GL_ANGLE_texture_compression_dxt5,
    * GL_EXT_texture_compression_dxt1
    * GL_EXT_texture_compression_s3tc
    * GL_S3_s3tc
    * GL_EXT_texture_compression_s3tc_srgb

This enables 206 passing piglit test related to gl_compressed.*s3tc_dxt
