  [mlir][tosa] Move lowering of `tosa.transpose` to `tosa-to-linalg-named` (#75738)

Currently, there exists a pattern lowering `tosa.transpose` to
`linalg.generic` in `tosa-to-linalg`.
This patch removes that and instead adds a pattern lowering
`tosa.transpose` to `linalg.transpose` in `tosa-to-linalg-named`.
Lowering to the named linalg Op has the advantage that following
optimization passes can easily identify transposition without having to
perform pattern matching on linalg.generic Ops. The `linalg.transpose`
can simply be generalized to a `linalg.generic` in a second step.
