feat: make repeat and while syntax builtin (#13442) 
This PR promotes the `repeat`, `while`, and `repeat ... until` parsers
from `syntax` declarations in `Init.While` to `@[builtin_doElem_parser]`
definitions in `Lean.Parser.Do`, alongside the other do-element parsers.
The `while` variants and `repeat ... until` get `@[builtin_macro]`
expansions; `repeat` itself gets a `@[builtin_doElem_elab]` so a
follow-up can extend it with an option-driven choice between `Loop.mk`
and a well-founded `Repeat.mk`.

The new builtin parsers are registered at `low` priority so that the
bootstrapping `syntax` declarations in `Init.While` (still needed for
stage0 compatibility) take precedence during the transition. After the
next stage0 update, the `Init.While` syntax and macros can be removed.
