fix(library/tactic/subst_tactic): in the standard mode, use dependent elimination in the subst tactic (when needed)

Before this commit, the subst tactic was producing an type incorrect
result when dependent elimination was needed (see new test for an example).

feat(library/tactic/inversion_tactic): consistent orientation of generated equalities

Generated equalities in proof irrelevant environments were inverted
compared with the documentation and the proof relevant case, which
resulted in newly generated local vars replacing equivalent old ones
instead of the other way around.

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.
