Allow swizzles to match with "undefined" components (#1538)

Browse Source 
* Add swizzle matching rules.

Improves rules which try to match incompatible formats as perfect, such as D32 float -> R32 float.

Remove Format.HasOneComponent, since this information is now available via the FormatInfo struct.

* Fix this rule.

* Update component counts for depth formats.
