refactor(library/util): use type_checker at to_telescope
...
The to_telescope abstraction is not very useful for
abstract_type_context.
Reason: Fun/Pi (kernel) procedures are not compatible with abstract_type_context.

fix(library/tactic): we must unfold untrusted macros when type checking intermediate results
...
Example: before this commit, the file librata/data/list/perm.lean would
not type check if the option -t 0 (trust level zero) was provided.
Reason: the intermediate term contained a macro, and macros are not
allowed at trust level zero.
