[projmgr] Adjust relative paths in misc nodes

[brondani]

Fixes

• https://github.com/Arm-Debug/uvprojx-converter/issues/426#issuecomment-4750308515
  Relative paths specified in misc node fields are not adjusted when projects are converted. This causes path references to become invalid in the generated *.cbuild.yml file.

Changes

• Added ProjMgrUtils::AdjustRelativePaths() to detect relative paths (./ or ../) in solution-, project-, and layer-level misc option fields, and adjust the original references across all supported misc node elements.
• Added test cases

Checklist

• 🤖 This change is covered by unit tests (if applicable).
• 🤹 Manual testing has been performed (if necessary).
• 🛡️ Security impacts have been considered (if relevant).
• 📖 Documentation updates are complete (if required).
• 🧠 Third-party dependencies and TPIP updated (if required).

Pull request overview

This PR fixes conversion output correctness by ensuring relative paths embedded in misc option strings (solution/project/layer level) are rewritten so they remain valid in the generated *.cbuild.yml files.

Changes:

• Added ProjMgrUtils::AdjustRelativePaths() and invoked it during misc option processing in ProjMgrWorker.
• Added a focused unit test for AdjustRelativePaths() plus an end-to-end conversion test covering misc fields at solution/project/layer scopes.
• Added new test fixtures (TestMiscRelativePaths) and a reference cbuild.yml for regression validation.
