go/runtime/registry: Simplify creation of provisioners

[peternose]

Trying to remove the bundle registry dependency from the createProvisioner function, as nodes should generally not have any bundles stored locally upon their initial startup.

These changes also decouple the creation of provisioners from TEE selection. Previously, only client nodes could choose the TEE in which a component would run. Now, node operators can specify the TEE for each component, provided the component supports the chosen TEE. If no TEE is specified, it is automatically selected, with TDX and SGX taking precedence over ELF.

How to configure nonSGX client:

runtime:
  paths: # Can be replaced with bundle repository url.
    - {{ runtime_orc_path }} 
  runtimes:
  - id: {{ runtime_id }}
    components:
    - id: ronl
      tee: none # Do not run in SGX or TDX!

How to configure SGX client:

runtime:
  paths: # Can be replaced with bundle repository url, if you also specify runtime ids.
    - {{ runtime_orc_path }}
  sgx_loader: /node/bin/oasis-core-runtime-loader

How to mock SGX:

runtime:
  paths: # Can be replaced with bundle repository url, if you also specify runtime ids.
    - {{ runtime_orc_path }}
  debug_mock_tee: true

Do we run client with RuntimeEnvironmentELF and without DebugDontBlameOasis flag set?

Yes I believe so: For example, running a ParaTime client node for an SGX-enabled ParaTime like Cipher doesn't require having SGX on the ParaTime client node..
