Default CMake Preset Setting in Workspace Settings

### Brief Issue Summary

Issue: When using multiple workspaces in the same directory, Visual Studio Code's CMake Tools extension does not remember individual CMake presets for each workspace. This leads to the inconvenience of frequently having to manually select the correct preset for each workspace.

Proposed Solution: Introduce a new setting, cmake.defaultConfigurePreset, in the workspace settings. This setting would allow users to specify a default CMake preset for each workspace.

Expected Benefit: This feature would automatically configure each workspace with its specified preset upon opening, simplifying the workflow and reducing manual configuration.

Review the extension's existing workspace settings and CMake preset selection flow first. Add the proposed cmake.defaultConfigurePreset setting so each workspace can retain and apply its selected preset when opened, then verify behavior with multiple workspaces sharing one directory.
