  Log Message:
  -----------
  [MLIR][Linalg] Introduce linalg.contract (#123618)

A new op that allows for representing arbitrary contractions on operands
of arbitrary rank, with arbitrary transposes and arbitrary broadcasts
specified through its indexing_maps attribute.

Supports the expected lowerings to linalg.generic and to
vector.contract.
