Adds UAX #44 identifier checking, and NFC quick check support, along with a few helpers like `isAscii` and `unescapeUnicode`.

Pull Request Overview
This PR introduces comprehensive Unicode support to the qtil library, providing CodeQL predicates for Unicode property checking, UAX #44 identifier validation, and NFC normalization checking. The implementation includes raw Unicode data generation, string utilities for Unicode escape handling, and efficient APIs for common Unicode operations.
- Adds extensible predicates for Unicode properties (enumeration, boolean, and numeric)
- Implements UAX #44 identifier validation and NFC normalization quick checking
- Provides utilities for Unicode escape sequences and ASCII validation

The comment and code handling ranges is duplicated on lines 128-130 and 157-159. Consider extracting this logic into a helper function to reduce duplication.

CodeQL coding standards is implementing MISRA rules that refer to unicode standard concepts such as UAX #44 compliant identifiers, and NFC normalization checks.
These concepts are neither specific to MISRA, nor C, and thus, deserve a home in qtil.
This pull request introduces
isAsciiandunescapeUnicodeQtil.qll.These features are pretty advanced, I'm not sure they're worth adding to the README.md.
