feat(build): Add bazel build system

[VoyTechnology]

Currently only added to Go targets.

Maintains full compatibility with the current source. This is more of an alternative than a complete replacement.

Benefits:

• Dependency version control
• Can be unified into a single build system for both Golang and Rust and Docker targets.
• Ensures consistent build
• In case of Go, allows the source code to be placed anywhere on the machine.

Caveats:

• BUILD files and WORKSPACE need to be maintained
• Looks like currently poor support for custom Rust toolchains (nightly)
• Can be a bit slow for the first time. Caching in CI would definitely be necessary
