Centralize and document TRACE tags using X-macros (#7657)

* Introduce X-macro-based trace tag definition
- Created trace_tags.def to centralize TRACE tag definitions
- Each tag includes a symbolic name and description
- Set up enum class TraceTag for type-safe usage in TRACE macros

* Add script to generate Markdown documentation from trace_tags.def
- Python script parses trace_tags.def and outputs trace_tags.md

* Refactor TRACE_NEW to prepend TraceTag and pass enum to is_trace_enabled

* trace: improve trace tag handling system with hierarchical tagging

- Introduce hierarchical tag-class structure: enabling a tag class activates all child tags
- Unify TRACE, STRACE, SCTRACE, and CTRACE under enum TraceTag
- Implement initial version of trace_tag.def using X(tag, tag_class, description)
  (class names and descriptions to be refined in a future update)

* trace: replace all string-based TRACE tags with enum TraceTag
- Migrated all TRACE, STRACE, SCTRACE, and CTRACE macros to use enum TraceTag values instead of raw string literals

* trace : add cstring header

* trace : Add Markdown documentation generation from trace_tags.def via mk_api_doc.py

* trace : rename macro parameter 'class' to 'tag_class' and remove Unicode comment in trace_tags.h.

* trace : Add TODO comment for future implementation of tag_class activation

* trace : Disable code related to tag_class until implementation is ready (#7663).
