This lifts the core of the jit_ir_importer and ltc out of the pt1 project, making them peers to it. As a side-effect of this layering, now the "MLIR bits" (dialects, etc) are not commingled with the various parts of the pt1 project, allowing pt1 and ltc to overlay cleanly onto a more fundamental "just MLIR" Python core. Prior to this, the Python namespace was polluted to the point that this could not happen.
That "just MLIR" Python core will be introduced in a followup, which will create the space to upstream the FX and ONNX pure Python importers.
This primary non-NFC change to the API is:
torch_mlir.dialects.torch.importer.jit_ir->torch_mlir.jit_ir_importer.The rest is source code layering so that we can make the pt1 project optional without losing the other features.
Progress on #2546.
