Migrate away from CMake and use Bazel

**Is your feature request related to a problem? Please describe.**
Handling C++ dependencies in CMake is difficult. Bazel makes a lot easier, especially since BinDiff needs the OSS Google stack (Abseil, Protobuf, etc. but later maybe gRPC)

**Describe the solution you'd like**
Bazel has decent support for Windows, Linux and macOS and its build files are easier to maintain.

**Describe alternatives you've considered**
N/A

**Additional context**
This should first be investigated, but it's definitely feasible, as we are building most of BinDiff with the internal version of Bazel already (including IDA plugins and the UI).
