Probable issue stemming through affine lowering not going through affine.apply for affine.delinearize/linearize op

[Abhishek-Varma]

PREVIOUS STATE:
-- affine lowering used to go through affine.apply for affine.delinearize/linearize op
-- mat_truncf_affine_apply.log
-- Here is the IR snippet to focus on

CURRENT STATE:
-- affine lowering doesn't used incorporate affine.apply for affine.delinearize/linearize op's lowering.
-- mat_truncf_not_using_affiny_apply.log
-- Here is the IR snippet to focus on

For both case use the "IR snippet to focus on" as the input.mlir and run the following :-

iree-opt --allow-unregistered-dialect --canonicalize input.mlir

For "PREVIOUS STATE", you'd see no builtin.unrealized_conversion_cast remains, while that's not the case for "CURRENT STATE".

The above issue arises ONLY for "Matmul + Truncf" related CI tests as observed here in the IREE bump PR because that's where we currently deal with affine.delinearize_index due to --iree-amdaie-enable-coalescing-loops
