As of https://github.com/llvm/llvm-project/pull/176387 and release 22, official builds of lldb on Windows use Python 3.11 both on x64 and arm64.

The Windows lldb build bots use 3.11+ versions of Python:

[lldb-x86_64-win](https://lab.llvm.org/buildbot/#/builders/211) - `3.12.7`
[lldb-remote-linux-win](https://lab.llvm.org/buildbot/#/builders/197) - `3.12.7`
[lldb-aarch64-windows](https://lab.llvm.org/buildbot/#/builders/141) - `3.11.9`

This patch changes the cmake config and documentation to recommend building lldb on Windows with Python 3.11 or more recent.

Given the reduced number of lldb maintainers on Windows compared to other platforms, bumping the Python version on Windows would help reduce the surface area of Python related bugs.
