feat: parity between structure instance notation and where notation (#6165) 
This PR modifies structure instance notation and `where` notation to use
the same notation for fields. Structure instance notation now admits
binders, type ascriptions, and equations, and `where` notation admits
full structure lvals. Examples of these for structure instance notation:
```lean
structure PosFun where
  f : Nat → Nat
  pos : ∀ n, 0 < f n

def p : PosFun :=
  { f n := n + 1
    pos := by simp }

def p' : PosFun :=
  { f | 0 => 1
      | n + 1 => n + 1
    pos := by rintro (_|_) <;> simp }
```
Just like for the structure `where` notation, a field `f x y z : ty :=
val` expands to `f := fun x y z => (val : ty)`. The type ascription is
optional.

The PR also is setting things up for future expansion. Pending some
discussion, in the future structure/`where` notation could have have
embedded `where` clauses; rather than `{ a := { x := 1, y := z } }` one
could write `{ a where x := 1; y := z }`.

e9d85f49e6 chore: remove tryPureCoe? 
Based on the discussion at
https://leanprover.zulipchat.com/#narrow/stream/270676-lean4/topic/for.2C.20unexpected.20need.20for.20type.20ascription/near/269083574
The consensus seemed to be that "auto pure" is more confusing than its worth.
