Speed up TeamCity build (#1803)

Fixes #1804

In an effort to speed up the CI-pipeline 2 changes have been made:
- After some investigation a bottleneck has been identified during the
CI-pipeline.
The CI build steps are run in docker containers. In this containers a
volume is mounted which contains the checkout repository. This is the
way TeamCity works.
When installing the pixi environment the environment the environment is
installed into this mounted volume. By moving the environment out of the
mounted volume to another location in the container a noticeable speedup
is achieved.
- The editable installation of imod has been changed from a task to a
pypi-dependency. This way it happens at the same time as when the pixi
environment is being installed, which results in a slight speedup

**Unrelated**
The mypy daemon kept crashing in vscode. The reason is that it
encountered some partial types when analyzing pyvista.
I've disabled following that import. Now its possible to use the daemon
i.c.w. the mypy extension in vscode, which should give you faster
feedback when new mypy errors popup
