feat: add quot_precheck for expression tree elaborators (binop%, etc.) (#3078) 
There were no `quot_precheck` instances registered for the expression
tree elaborators, which prevented them from being usable in a `notation`
expansion without turning off the quotation prechecker.

Users can evaluate whether `set_option quotPrecheck false` is still
necessary for their `notation` definitions.
