Support Environment Configs

[stevendborrelli]

What problem are you facing?

Support generating manifests with EnvironmentConfig support

How could Crossplane help solve your problem?

Add support for top level environment config, (patches, selectors, etc.) and setting ToEnvironmentFieldPath and FromEnvironmentFieldPath.

@stevendborrelli after we merge https://github.com/crossplane-contrib/x-generation/pull/29 we have the option to use EnvironmentConfig like this - does this makes sense for your ?
