configure.ps1: Fix path handling and improve reliability

- Use $PSScriptRoot for reliable source directory detection
- Use Join-Path for proper path construction
- Validate BUILD_TYPE against Debug/Release
- Fix CMake argument quoting
- Use Write-Error for error messages

-## ExectOS Ideas
-This is a list of ideas that migh but not must be realized.
-
-### XTOSKRNL
- - [ ] Implement mechanism for detecting CPU features and checking hardware requirements. If CPU does not meet
-       requirements, it should cause a kernel panic before any non-supported instruction is being used.
- - [ ] Finish framebuffer and terminal implementation. Initialization code is already prepared as well as routines for
-       clearing the screen and drawing single points. Terminal should be instantiable (should be able to create many
-       terminals and switch between them) and work on top of FB. It should define ANSI colors and scrollback buffer.
