libcamera: controls: Make ControlValue get/set accessors template methods

Browse source 
The ControlValue get accessors are implemented with functions of
different names, whlie the set accessors use polymorphism to support
different control types. This isn't very consistent and intuitive. Make
the API clearer by using template methods. This will also have the added
advantage that support for the new types will only require adding
template specialisations, without adding new methods.
