Add jdwp support

[Daquiver1]

This PR tackles issue #56.
It creates a module for the JDWP commands and errors over here

Great start !

I have a suggestion to organize code a bit differently. I would:

• move Type, Field, Struct, Command and Command set to projects/jdwp/defs/schema.py
• move all remaining enums to projects/jdwp/defs/constants.py
• move definitions of command sets to projects/jdwp/defs/commandsets/...

Not all commands are correctly described. In particular, some of them should have array fields and this PR does not add support for Arrays. Let's extract a part of this PR that can be landed sooner and will unblock @wekesa360.

Could you please do the following:

• address feedback in schema.py and constants/*.py
• move all definitions of constants to defs/constants.py
• for now remove
  • defs/commands/thread_reference.py and defs/command_sets/thread_reference.py
  • all commands fromdefs/commands/reference_type.py but the Signature command
• move definition of Signature from defs/commands/reference_type.py to defs/command_sets/reference_type.py
• make ReferenceType command set incomplete, consisting of only one command (Signature) for now
• rebase on top of main and make sure code builds with buck and checks with pyre.

Could you also start files with this copyright ?

Almost perfect!

Pyre does not type check new files because they are not part of any buck target. Could you add
projects/jdwp/defs/BUCK file with the following content ?

# Copyright (c) Meta Platforms, Inc. and affiliates.

python_library(
    name = "defs",
    srcs = glob(["**/*.py"]),
    visibility = ["PUBLIC"],
)

This will make all the new files visible to buck and pyre.

This is not projects/jdwp/defs/BUCK, but that is fine. In this case please keep the original name ("lib") and we should be good to go.
