Christian Blichmann 6a58a29039 Make CMake superbuild behave more similar to FetchContent
- Move CMake superbuild files
- Drop use of `CMakeLists.txt.in` configure files
- Allow overriding dependency directories. For now, this should only be
  used by GitHub workflows. Will be expanded on later, possibly renaming
  the variables.

This change is one in a series to make it easier to consume/customize
Sandboxed API in downstream projects.

Drive-by:
- Update `.gitignore` to ignore clangd's `.cache` directory
