[dartdevc] fix #36372, make JS Array constructor property usable from JS

The `new array.constructor()` pattern is occasionally used in JS
(presumably, to get the array subtype if one is available). GopherJS in
particular does this. This fixes DDC's generic `JSArray<T>` to support
this pattern, for all values of T. This also makes JSArray work like
all other "native" types in DDC, where the "constructor" property
is the JS constructor for that native type.
