Bazel: read dependencies.yaml on the fly

[golovasteek]

Describe your changes

Before this PR, for every change in the dependencies.yaml we had to to run bazel run //:update to re-generate bazel files, which was an annoying extra step.

This change moves the code that generates bazel dependencies into edm tool, and bazel leverages it to generate dependencies on the fly.

So there is again just one file with all the dependencies.
