anv/formats: Add an anv_get_format helper

This commit removes anv_format_for_vk_format and adds an anv_get_format
helper.  The anv_get_format helper returns the anv_format by-value.  Unlike
anv_format_for_vk_format the format returned by anv_get_format is 100%
accurate and includes any tweaks needed for tiled vs. linear.
anv_get_isl_format is now just a wrapper around anv_get_format that picks
off just the isl_format.
