[JSC] move function wrapping logic to a new Function type

JSTests:
Adds a new file testing CopyNameAndLength stuff in the ShadowRealm proposal,
and fix up assertions about this in shadow-realm-evaluate.js
- stress/shadow-realm-evaluate.js:
- stress/shadow-realm-remote-function-copy-length-and-name.js: Added.
Source/JavaScriptCore:
In this initial patch, there is still a lot of JS-builtin machinery,
including some duplicated functionality. Additionally, JIT support
has not been incorporated yet.
Broadly, the idea is that there are custom hooks for calling a
JSRemoteFunction, which perform the wrapping functionality. This avoids
the need for allocating closures which contain the wrapping logic.
TODO:
- JIT/DFG/FTL support
- structure caching (unnecessary since these are not constructors?)
- improved baseline perf
