tdf#70280 Add UNOIDL support to ctags

This supports the UNOIDL language constructs Enumeration, ElementName,
Structure, Interface, FunctioName, Service, and PropertyName.

The values are mapping to ctags as:

UNOIDL          ctags

Enumeration     e,enum
ElementName     m,member
Structure       s,struct
Interface       i,interface
FunctioName     f,function
Service         g,service
PropertyName    p,property
