feat: termination_by? ( #3514 )
...
the user can now write `termination_by?` to see the termination argument
inferred by GuessLex, and turn it into `termination_by …` using the “Try
this” widget or a code action.
To be done later, maybe: Avoid writing `sizeOf` if it's not necessary.

fix: make omission syntax be a builtin syntax
...
When editing core Lean, the `pp.proofs` feature causes goal states to fail to display in the Infoview, instead showing only "error when printing message: unknown constant '«term⋯»'". This PR moves the `⋯` syntax from Init.NotationExtra to Lean.Elab.BuiltinTerm
It also makes it so that `⋯` elaborates as `_` while logging a warning, rather than throwing an error, which should be somewhat more friendly when copy/pasting from the Infoview.
Closes #3476

feat: per-function termination hints
...
This change
* moves `termination_by` and `decreasing_by` next to the function they
apply to
* simplify the syntax of `termination_by`
* apply the `decreasing_by` goal to all goals at once, for better
interactive use.
See the section in `RELEASES.md` for more details and migration advise.
This is a hard breaking change, requiring developers to touch every
`termination_by` in their code base. We decided to still do it as a
hard-breaking change, because supporting both old and new syntax at the
same time would be non-trivial, and not save that much. Moreover, this
requires changes to some metaprograms that developers might have
written, and supporting both syntaxes at the same time would make
_their_ migration harder.
