fix(cli): sanitize SwiftPM prebuilt paths

Resolves https://github.com/tuist/tuist/issues/YYY

This fixes two SwiftPM prebuilt integration issues that show up with precompiled SwiftSyntax packages:

• Sanitizes control characters from paths decoded out of workspace-state.json before converting them to AbsolutePath or RelativePath.
• Reuses the existing /private/var normalization through the same path sanitization boundary for dependency, artifact, prebuilt, checkout, and include paths.
• Adds the prebuilt library directory to LD_RUNPATH_SEARCH_PATHS so macro executables can locate Swift compatibility dylibs such as libswiftCompatibilitySpan.dylib at runtime.
• Covers both the path sanitization and runtime search path behavior in TuistLoaderTests.

How to test locally
