Fix cmdstanpy install issue with pip

[swotai]

Description

In Windows using the windows store's python distributions and venv, installation of the package would break during installation of cmdStan and creation of the complied stan binaries. This is caused by usage of temp folder, having to move things around from temp to package directory, as well as missing complier in Windows.

Fix: Simplified setup.py workflow by aligning installing workflow with non-window machines. Adds complier=True flag to cmdstanpy.install_cmdstan. Tested on python 3.9-3.11 venvs.

Fixes #808
