Get rid of 'read_hkd' by refactoring the 'get_verified_hkds' function.
For this a new HkdLoader::load_and_verify is introduced that is a
reworked version of the original code.
In addition, add test cases for testing all the edge cases.

Replace version-specific flag enums (PcfV1, ScfV1) with a unified
SeHdrFlag enum and generic ControlFlagsModel. This refactoring provides:
- Single SeHdrFlag enum for all control flags across SE header versions
- Generic SeHdrControlFlagsModel with version-specific configurations
- EffectiveControlFlags type replacing PlaintextControlFlagsV1/SecretControlFlagsV1
- FlagsOverride mechanism for customizing flag configurations
- Enhanced FromStr implementation for flag parsing
- Comprehensive test coverage for flag operations and conversions
The new design improves maintainability by eliminating code duplication
and provides a more flexible API for working with SE header control
flags.

The new Rust port of genprotimg will have the name 'pvimg' as it has
more functionalities than the original genprotimg tool. As preparation
add a Secure Execution header library and an example how to use it. The
example can be used by the KVM-Unit-Tests for creating the Secure
Execution headers needed by the tests [1].
[1] See dc4f7106f3
more information how to use.
