Implicit parameters for builtins with JavaScript linkage are now separate, using
the keyword "js-implicit". They have to be one of:
- context: Context
- receiver: Object (this in JS)
- target: JSFunction (arguments.callee in JS)
- newTarget: Object (new.target in JS)

Introduce a single point to emit CodeCreateEvents for all builtins in
Isolate::Init. At this location, we cover both the case of builtin generation
(e.g. in mksnapshot) and deserialized builtins (in standard builds),
whereas previously we only emitted events post-builtin-generation.
In order to preserve behavior for bytecode handler events, pack the bytecode
and operand scale into our existing builtin metadata table.

Macros are now inaccessible from CSA except if their declaration is
marked with the "export" keyword. The implicit field accessors for class
fields are always exported.
In this CL, unwarranted access from CSA is prevented by appending a
pseudo-random suffix to non-exported names. This is to be replaced by
something more principled, namely by not including these macros at all in
the headers included from CSA.

does require reordering the fields within Map to abide by Torque rules
specifying that strong and weak fields must be in separate sections.
Also includes some Torque compiler updates:
- Allow enums (types extending from integral types) as class fields
- Rename @ifdef to @if and add @ifnot for inverse checks
- Allow void fields in class declarations, which take up no space and
emit no accessors
