This adds
- `mlir::tosa::populateTosaToLinalgTypeConversion` which converts
tensors of unsigned integers into tensors of signless integers
- modifies the `tosa.reshape` lowering in TosaToTensor to use the type
converter correctly
I choose to implement the type converter in
`mlir/Conversion/TosaToLinalg/TosaToLinalg.h` instead of
`mlir/Conversion/TosaToTensor/TosaToTensor.h` because I need the same
type converter in the TosaToLinalg lowerings (future PR).
Alternatively, I could duplicate the type converter so it exists both in
TosaToLinalg and TosaToTensor. Let me know if you prefer that.
tosa.reshape and tosa.concat were moved from TosaToLinalg to TosaToTensor
(D145119 & D145952). So now they are legal after applying TosaToLinalg patterns,
and illegal after applying TosaToTensor patterns.
This includes D146174 (thanks @ramiro050!)

Since tosa.pad is lowered strictly to artih and tensor ops, move
ConvertPad from TosaToLinalg to TosaToTensor, benefitting non-Linalg
Tosa targets. TensorToLinalg exists, and is trivial, so nothing is lost.

The patch introduces the required changes to update the pass declarations and definitions to use the new autogenerated files and allow dropping the old infrastructure.

Apply scale should be optionally disabled when lowering via TosaToStandard.
In most cases it should persist until the lowering to specific backend.
