Generate enumeration storage width

[vivien-apple]

Problem

Currently enum are using uint32_t for their storage witdth

Change overview

• Use the type specified in the enum definition

Testing

• Manually tested by generating + compiling on Mac. Someone with a platform that was not compiling (for example uint32_t came from use the enumeration with an fixed underlying type #7266 because of some compilation issues) may want to double check it

#Fixes #7394 ?
