platform/x86/intel/pmt: Add pre/post decode hooks around header parsing
Add optional pre- and post-decode callbacks to the PMT class so namespaces
can perform setup and cleanup steps around header parsing.
- Add pmt_pre_decode() and pmt_post_decode() to struct
intel_pmt_namespace.
- Update intel_pmt_dev_create() to invoke, in order:
pre → header_decode() → post.
- Keep the existing pmt_header_decode() callback unchanged.
No functional changes. This adds flexibility for upcoming decoders while
preserving current behavior.
