Instead of creating a separate code object per exported function, we
can share the code per signature, and load the function index from the
{WasmExportedFunction} object which is being passed as an argument
anyway.
This greatly reduces instantiation time for modules with a lot of
exports.
As a next step, we could even share the code across instances, or (with
more work) across isolates.

This is a clean-up to completely remove the Heap accessors for roots
accessible via ReadOnlyRoots. Where previously ReadOnlyRoots called the
Heap accessor, now it accesses the roots array directly using the root
index (since ReadOnlyRoots is a friend of Heap).

Also clean up several cases where private Heap accessors were still
being used by Heap and its friends.

RegExp builtins were the first to be ported to CSA roughly two years
ago. Back then, we weren't really aware of issues surrounding code
size and CSA inlining, and thus some of these builtins were bigger
than they should be.

This CL adds a few new helper builtins and removes inlined calls to
SubString, RegExpExecInternal, and StringAdd. It significantly
reduces the size of affected builtins. Minor performance regressions
due to call overhead are expected.

Before:
TFS Builtin, RegExpReplace, 20008
TFS Builtin, RegExpSplit, 17340
TFS Builtin, RegExpMatchFast, 17064
TFJ Builtin, RegExpStringIteratorPrototypeNext, 12862

After:
TFS Builtin, RegExpReplace, 5067
TFS Builtin, RegExpSplit, 6329
TFS Builtin, RegExpMatchFast, 8164
TFJ Builtin, RegExpStringIteratorPrototypeNext, 6652

When calling an import which is an exported wasm function, the
interpreter needs to look through the jump table to find the

We already had that logic for indirect calls, but it was missing for
