Libraries: Implement SemVer for version parsing and comparisons

Browse source 
Semantic Versioning (SemVer) is a versioning scheme for software that
uses MAJOR.MINOR.PATCH format. MAJOR for significant, possibly
breaking changes; MINOR for backward-compatible additions; PATCH for
bug fixes. It aids communication, compatibility prediction, and
dependency management. In apps dependent on specific library versions,
SemVer guides parsing and validates compatibility, ensuring apps use
appropriate dependencies.

    <valid semver> ::= <version core>
                     | <version core> "-" <pre-release>
                     | <version core> "+" <build>
                     | <version core> "-" <pre-release> "+" <build>
