chore: ensure all instances referred to directly have explicit names (#6423)

Per https://github.com/leanprover/lean4/issues/2343, we are going to need to change the automatic generation of instance names, as they become too long.

This PR ensures that everywhere in Mathlib that refers to an instance by name, that name is given explicitly, rather than being automatically generated.

There are four exceptions, which are now commented, with links to https://github.com/leanprover/lean4/issues/2343.

This was implemented by running Mathlib against a modified Lean that appended _ᾰ to all automatically generated names, and fixing everything.

feat: quick version of mono tactic (#1740)

This is an extremely partial port of the mono* tactic from Lean 3, implemented as a macro on top of solve_by_elim. The original mono had many configuration options and no documentation, so quite a bit is missing (and almost all the Lean 3 tests fail). Nonetheless I think it's worth merging this, because

  • it will get rid of errors in mathport output which come from lemmas being tagged with a nonexistent attribute @[mono]
  • in most mathlib3 uses of mono, only the basic version was used, not the various configuration options; thus I would guess that this version of mono will succeed fairly often in the port even though it fails nearly all the tests

  • take all mathlib 3 names, remove _ and make all uppercase letters into lowercase
  • take all mathlib 4 names, remove _ and make all uppercase letters into lowercase
  • look for matches, and create pairs (original_lean3_name, OriginalLean4Name)
  • for pairs that do not have an align statement:
    • use Lean 4 to lookup the file + position of the Lean 4 name
    • add an #align statement just before the next empty line
  • manually fix some tiny mistakes (e.g., empty lines in proofs might cause the #align statement to have been inserted too early)
