patina-v21.0.1

What's Changed

• [patina\_mm] refactor current folder structure to allow external consumption @kuqin12 (#1413)
  
  Change Details

    ## Description

  Current patina_mm carries some definitions that can be shared by external users (mm communication header, buffer status, etc).

  This change moves those files to a sub-module that does not require alloc.

  It also separates the supervisor related definitions into its own file.

  Resolves #1437.

📖 Documentation Updates

• Add unsafe CPUID support for Rust `<=1.93` Toolchains @kouchekiniad (#1448)
  
  Change Details

    ## Description

  This change adds unsafe { } wrappers around the patina_dxe_core's use of __cpuid, adding back support for Rust <= 1.93 toolchains where these are considered unsafe calls. To prevent warnings about these wrappers being unnecessary on Rust >= 1.94 (or >= nightly-2025-12-27) toolchains, this change additionally adds #[allow(unused_unsafe)] declarations to the wrappers.

  This change additionally updates the patina-mtrr dependency to a version which adds these same wrappers to it's own usage.
