This CL is pretty mechanical; I just iterated through some Torque
classes making the following changes:

- Use @generateCppClass if it seems easy to
- Use @generatePrint if the existing printer doesn't do anything special
- Fix up any imprecise field types

It also includes two minor changes to implementation-visitor:

- Add a new -inl.h file with the things needed for
  torque-generated/class-definitions-tq.cc so we don't need to keep
  changing the compiler when we add @generateCppClass.
- Avoid emitting incorrect accessors for ExternalPointers. This isn't
  strictly necessary for correctness, as the accessors defined in C++
  already hide the ones inherited from generated code, but it makes me
  feel safer.

This creates a .tq file in src/objects for each src/objects/*.h file
with Torque-defined classes and moves the object definitions and
corresponding helpers/macros there.
In addition, we create files convert.tq and cast.tq in src/builtins
to move the casts and conversions to.

Since Torque-generated .cc files end up as .o files in the same
directory, there cannot be two .tq files of the same name. Thus it
was necessary to rename src/builtins/arguments.tq and
src/builtins/string.tq to not clash with the new files in src/objects.

This is a mechanical change that only moves code.

- Add a new ClassScope for block scopes created for classes.
- Add a VariableMap in the class scope for private name resolution,
  and a separate UnresolvedList for private names that will be resolved
  only using ClassScopes. These are stored in RareData and will only be
  allocated when there are private name declaration or access in the
  class.
