Implement validate_tables: sorted table verification and Ptr table checks

[Copilot]

• Add mdc_uncompressed_table_heap flag to mdcxt_flag_t in internal.h
• Set the flag in md_create_handle in entry.c when tables_heap_uncompressed is true
• Set the flag in create_and_fill_indirect_table in editor.c when Ptr tables are introduced via edit APIs
• Use mdc_uncompressed_table_heap flag in md_write_to_buffer for #- stream name selection instead of mdc_minimal_delta
• Implement validate_tables in streams.c:
  • Validate that *Ptr tables (FieldPtr, MethodPtr, ParamPtr, EventPtr, PropertyPtr) are not present in a compressed table heap (#~)
  • Validate that tables marked as sorted are actually sorted (using sort keys from get_table_keys)
• Align equals signs in mdcxt_flag_t enum
• Restore ECMA-335 TODO comment
• Build and test (all 30 emit tests pass)

Original prompt

Implement the TODOs in the validate_tables method.

@copilot update the logic in md_write_to_buffer to use the #- stream based on the new uncompressed flag you added instead of the minimal delta flag.

@copilot update the logic in md_write_to_buffer to use the #- stream based on the new uncompressed flag you added instead of the minimal delta flag.

Done in 6f95ee2 — md_write_to_buffer now uses mdc_uncompressed_table_heap to choose between #- and #~ for the table stream name. The mdc_minimal_delta check is kept only for the #JTD stream count increment. The redundant indirect table loop check was also removed since the flag already covers that case.

All three items addressed in 6e3ee0c — enum alignment, restored ECMA-335 TODO, and updated Ptr comment.
