This is based on the MLIR opt kernel:
https://github.com/llvm/llvm-project/tree/main/mlir/utils/jupyter

The inent of this is to enable experimentation and the creation
of interactive tutorials for the basics of tablegen.

Noteable changes from that:

- Removed the codemirror mode settings since those won't exist for tablegen.
- Added "%args" "magic" to control arguments sent to llvm-tblgen.

(magics are directives, see
https://ipython.readthedocs.io/en/stable/interactive/magics.html)

For example the following:

  %args --print-detailed-records
  class Stuff {}
  
  def water_bottle : Stuff {}

Produces:

  DETAILED RECORDS for file -
  
  -------------------- Global Variables (0) --------------------
  
  -------------------- Classes (1) --------------------
  
  Stuff  |<stdin>:1|
    Template args: (none)
    Superclasses: (none)
    Fields: (none)
  
  -------------------- Records (1) --------------------
  
  water_bottle  |<stdin>:3|
    Superclasses: Stuff
    Fields: (none)
