Resolve "Windows: Linker errors with protobuf-generated code"

Summary

Related to #90 (closed)

• Moves grpc- and protobuf-generated code into a static library called caosdb_grpc
• Statically links all other targets to this static library.
• Change output folder of tests to the same as the shared libraries. (CMAKE_BINARY_DIR)
• Build tests for both Debug and Release build types (#92 (closed), not yet part of the pipeline)
• Adds make-like PowerShell script (make.ps1) for easily building on Windows.

Building libraries, cli clients and tests now completes without errors.

Focus

Point the reviewer to the core of the code change. Where should they start reading? What should they focus on (e.g. security, performance, maintainability, user-friendliness, compliance with the specs, finding more corner cases, concrete questions)?

Test Environment

Follow build instructions in the updated Install_develop.rst. Basically,

• Install Visual Studio 2022 with CMake
• Install Python Conan env
• Run .\make.ps1 all
