Tweak the string-splitting to more closely match the intent of versions found in tooling, specifically: * Document that build metadata (`+foo` in `0.0.1+foo`) is always split out and not part of the canonical name. * Don't split out pre-release information since pre-release versions are incompatible with all other versions. This additionally matches preexisting merging behavior in `wit-component` as discovered in bytecodealliance/wasm-tools#2622

emit_canonical_namesflag enabled, so that we convert all binaries into their canonical encoding as a preprocessing step. Thenwaccan merge the interface via string matching directly.
