Migrate away from CMake and use Bazel

[cblichmann]

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).
