Add Xcelium script format

Add Cadence Xcelium as a new script format target. The template generates
-makelib/-endlib blocks per dependency package with per-group incdirs and
defines, while root package files are emitted as bare entries.

- Add Xcelium variant to ScriptFormat with --relative-path option
- Default targets: xcelium, simulation
- Add name field to TplSrcStruct (package name from source group)
- Add root_package to template context for root vs library distinction
- Add xcelium_f.tera template with hyphen-to-underscore library name
