v3dv: mark some promoted extensions as supported

There are few EXT_ extensions that were promoted to KHR_, but we didn't
enabled them as supported.

This makes some CTS tests to be run as unsupported when they should be
supported instead.

For example, we were passing 16/108 line rasterization tests instead of
40/108 because we did not enabled KHR_line rasterization.
