[CK_TILE] Add conv bwd data tests (#5646)

## Motivation
This PR adds tests for CK Tile's convolution backward data operation to
enable functionality regression tracking and error-detection.

## Technical Details
Currently only NHWGC/GKCYX/NHWGK and NDHWGC/GKCZYX/NDHWGK(2 dim and 3
dim channel-last) layouts are being tested, since only they are
implemented in CK Tile. Current tests support FP16, BF16 and FP32
datatypes and various different convolutions scenarios. The tested
instances are listed in
`experimental/grouped_convolution_tile_instances` directory.

## Test Result
All implemented tests are working properly and passing.
