libcamera: controls: Add enum names and values map to ControlId

Add to ControlId information about the names and values of enum, in the
event that the ControlId is an enum type. This allows applications to
query the ControlId for the names of the enum values, so that they can
be displayed on a UI, for example. Without this, it was necessary to use
macros of NameOfControlNameValueMap, which is difficult to use and is
very inflexible.

There already exists a map from name -> value in generated code. Reuse
this and pass it to the ControlId constructor, which in turn generates
the reverse map. The reverse map is then exposed to applications.
