Added support for multiple services scenario

[raych1]

Resolved #39974

Key Changes :

• Added findAllParentsWithFile function that traverses upward and collects all matching files instead of stopping at the first match

• Updated searchRelatedParentFolders function with an optional findAll parameter

• The new traversal logic is used when using the V2 folder structure, and t old folder structures (without resource-manager/data-plane) remain unchanged

Test PRs :

• Draft: Regression test - old folder structure (ContosoWidgetManager) #40237
• Testing multiple services sdk generation #40241
• Update tspconfig.yaml with new content #40242

Pull request overview

Adds multi-project support for TypeSpec “folder structure v2” in spec-gen-sdk-runner by allowing upward traversal to collect all matching tspconfig.yaml parents (instead of only the nearest), enabling SDK automation to react to changes at multiple service/subservice layers.

Changes:

• Introduces findAllParentsWithFile and extends searchRelatedParentFolders with an optional findAll mode.
• Enables findAll for TypeSpec project detection in detectChangedSpecConfigFiles.
• Expands fixtures and tests to cover multi-project v2 layouts under resource-manager/ and data-plane/.
