Align CMSIS-Core version sources to 6.3.0 across M/A/R profiles

[Copilot]

Version metadata for CMSIS-Core was out of sync across pack descriptor, header macros, and docs (M/A), causing conflicting reported CORE versions. This change standardizes the next release version to 6.3.0 in all required sync points.

• Scope: metadata alignment

  • Updated ARM.CMSIS.pdsc CORE components (condition="ARMv6_7_8-M Device", ARMv7_8-A Device, ARMv7-R Device) to Cversion="6.3.0".

• Scope: authoritative header macros

  • Updated CMSIS/Core/Include/cmsis_version.h:
    • __CM_CMSIS_VERSION_SUB → 3U
    • __CA_CMSIS_VERSION_SUB → 3U
    • __CR_CMSIS_VERSION_SUB → 3U
  • Main version macros remain 6U, yielding profile versions 6.3.

• Scope: documentation sync (M/A)

  • Updated Doxygen PROJECT_NUMBER:
    • CMSIS/Documentation/Doxygen/Core/Core.dxy.in → Version 6.3.0
    • CMSIS/Documentation/Doxygen/Core_A/Core_A.dxy.in → Version 6.3.0
  • Added V6.3.0 top revision row in:
    • CMSIS/Documentation/Doxygen/Core/src/history.md
    • CMSIS/Documentation/Doxygen/Core_A/src/history.md

/* cmsis_version.h */
#define __CM_CMSIS_VERSION_MAIN  ( 6U)
