* 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).
