Instead of passing four arguments to the runtime function, just pass one pointer to a struct containing all information. This makes it much easier to implement memory tracing in Liftoff in a follow-up CL. Also fix a few other minor things like the namespace and the include guards.

For JSCreate nodes with constant inputs we cannot simply assume that the new.target input is a JSFunction, since it can essentially be any JSReceiver that is a constructor, i.e. it can also be a JSBoundFunction.

Since we only need to store 18 different function kinds, the bitfield approach was wasting space (requiring 11 bits). This patch replaces the bitfield with a regular enum, and updates all the FunctionKind predicates to use comparisons instead of bitwise ops. For the small amount of builtin code that depended upon being able to do masking to determine whether something is a class constructor, we still store two extra bits on FunctionKind, which are computed when the SFI is initialized. If this approach causes performance regressions (i.e., if it turns out that other code was implicitly depending on masking for fast checks), we can revert this or address it in other ways (e.g., by doing similar caching of repeated checks in the caller).

This adds a reduced version of bot_default with only d8-based test suites. Those can be used for gc stress testing, fuzzing and predictable mode. This also adds a missing explicit build rule for the debugger test suite. It's working as it's part of the isolate file, but incremental re-isolation might break on code changes. Running the tests is still commented out to allow the infra-side to land. Afterwards, we'll activate the extra testing as a V8 CL commenting the lines back in.

This is justified because both functions only return values in the positive range of signed integer.
