Environments: Fix environment configuration (#42058)

Browse Source 
* Environments: fix environment config
* Don't change the lockfile manifest path
* Update activate's comments to tie the manifest to the configuration
* Add spec_list override method
* Remove type checking from 'activate' since already have built-in check
* Refactor global methods tied to the manifest to be in its class
* Restore Environment's 'env_subdir_path' and pass its config_stage_dir to EnvironmentManifestFile
* Restore global env_subdir_path for use by Environment and EnvironmentManifestFile
