Use a modifiable user-preset sample for VS 2022/2019 (#97)

* Use a modifiable user-preset sample for VS 2022/2019

Customizing a repo-tracked preset file doesn't work:

Type in your gamedir for debugging, or toggle verbose mode for the build, or configure Chinese
UB MapEditor: you now have an unstaged `CMakePresets.json` change in your working directory.
very annoying.

Also, Visual Studio 2022's preset support has a bug: if you have a `CMakePresets.json` file,
no matter in which file (user or repo) the preset you have selected is defined, if you click
"Manage Configurations..." it will always open `CMakePresets.json` for editing, setting the
user up for failure and editing the commited-to-repository file.

Having just the `CMakeUserPresets.json` file also sidesteps another poor Visual Studio 2022
decision: hiding in Folder View files that are .gitignore'd (like `CMakeUserPresets.json`).

In the absence of a `CMakePresets.json` file, selecting "Manage Configurations..." will open
the right file for editing.

The workflow is then:

Copy `CMakeUserPresets.json.sample` into `CMakeUserPresets.json` _once_, then customize
that to your heart's content without git bothering you and accidentally adding an
unwanted change to a patch. Or make your own.

* Added auto-copy of profile template.

* declutter things a bit

move function out of root cmakelists.txt file
move user preset template to a presets directory

this is horrible and I hate it
