mesa/format_utils: Add a function to convert a mesa_format to an array format
This commits adds the _mesa_format_to_array function that determines if the
given format can be represented as an array format and computes the array
format parameters. This is a direct helper function for using
_mesa_swizzle_and_convert
v2: Better documentation and commit message
v3: Fixed a potential segfault from an invalid endianness swizzle
