Support using chain-spec-builder for chain_spec_command

[pandres95]

Is your feature request related to a problem? Please describe.

As of now, zombienet only supports chain-spec-generator-like binaries on the parachains.chain_spec_command option.

This is a roadblock for those teams trying to free ourselves from maintaining client code (and commandline tools as well), since this kind of binary is still required to run zombienet whenever needed.

Describe the solution you'd like

A couple new options:

• chain_spec_builder_command, indicates zombienet where to find the binary for chain-spec-builder. This option is mutually exclusive with chain_spec_command.
• runtime_path the path of the runtime, used by chain_spec_builder_command.

When these options are enabled, a new mode based on chain-spec-builder should be used to produce the full and raw chainspecs.
