tylerjenningsw ca590aaead Expressions: a layer is made once per evaluation, and only functions are checked for being one
A Layer is now a callable function with its own prototype, which costs
more to make than the plain object it was. __layer(c, l) makes each
layer once per evaluation (kept in __S, which __begin resets), so an
expression naming the same layer many times builds it once. That covers
thisComp.layer(...) in a loop, .parent, a Layer Control's value and
thisLayer.

The checks for a layer (the result, thisComp.layer(layer, offset), the
property proxy) read __isLayer only on functions. Numbers and other
primitives are no longer boxed to look the property up.

Timing (release, Windows, medians of 2000 evaluations, PR vs main):
- one evaluation building one layer: about 22 vs 16 us;
- thisLayer.transform.opacity: about 200 vs 170 us;
- 20000 thisComp.layer(1) lookups in one evaluation: 95 vs 138 ms.
