fix(library/type_context): allow assigned regular meta-variables to be "read" in tmp-mode
...
This commit also removes a "hack" that tried to fix this problem for
universe meta-variables only. Moreover, the hack was incomplete, since
it would not consider nested metavars.

refactor(metavar_context): metavar_decl contains a local_context instead of local_decls
...
Motivations:
- A goal is essentially a metavar_decl
- We need the local_context to implement restrict_metavars_context method
