Nikolaj Schlej 934ce1f3f8 Kaitai-based Intel ACM and BootGuard parsers 
As the first step towards automated parsing, this change set replaces outdated BootGuard-related parsers with shiny new KaitaiStruct-based ones.
It also does the following:
- improves Intel FIT definitions by using the relevant specification
- adds sha1, sha384, sha512 and sm3 digest implementations
- updates LZMA SDK to v22.01
- moves GUIDs out of include files to prevent multiple instantiations
- enforces C++11
- adds Kaitai-based parsers for Intel FIT, BootGuard v1 and BootGuard v2 structures
- makes many small refactorings here, there and everywhere
