Normalize drive letter on windows for presets expanision

[Danielmelody]

This changes is a workaround for microsoft/vscode#156781

The following changes are proposed:

When expanding macros for CmakePresets.json on windows, the drive letter will now be re-normalized to uppercase.

The purpose of this change

When access workspaceFolder by uri, VScode normalize drive letter on windows to lowercase for historical reason. This behavior will cause all expanded path start with a lowercase drive letter, while Visual Studio, at the same time, expanding it as uppercase. If a user is switching vscode and Visual Studio, they would have to regenerate cmake cache as cmake count all those paths as a different variables.

Sorry for the silence. We've been finishing up the remaining tasks for the 1.12 release which has taken a bit longer than expected. We're almost done and then we will come back to the outstanding PR's.

Something changed in CI to make that test flaky. We'll rerun the test until it clears out. You don't need to worry about it.
