Add a new EnumNamingStrategy SPI which can be used for customising the way enums are matched by name.
It is similar to the AccessorNamingStrategy such that it allows implementors to provide a custom way of defining a property.
Related to #796, #1220, #1789 and #1667
Add a new custom EnumTransformationStrategy SPI which can be used for providing custom way of name based mapping for enums.
Add 4 out of the box transformation strategies:
* prefix - add a prefix to the name based enum mapping
* stripPrefix - remove a prefix from the name based enum mapping
* suffix - add a suffix to the name based enum mapping
* stripSuffix - remove a suffix from the name based enum mapping
This can be achieved by using the new `EnumMapping`
e.g.
Add suffix `_TYPE` to all enums:
`@EnumMapping(nameTransformationStrategy = "suffix", configuration = "_TYPE")`
With this it would be possible to achieve what is needed in #796, #1220, #1789.
