[CK] Add BF16^3 support to grouped conv bwd weight: bilinear and scale (#4591)

## Motivation

Until now, XDL grouped conv bwd weight for bilinear and scale only
supported bf16f32bf16.
Therefore, bf16bf16bf16 support should be added.

## Technical Details

Instances were added to the relevant files in
`library/include/ck/library/tensor_operation_instance/gpu/grouped_conv_bwd_weight/`
folder. In addition, `add()` functions were included in new files in
`library/src/tensor_operation_instance/gpu/grouped_conv3d_bwd_weight_bilinear/xdl/`
and
`library/src/tensor_operation_instance/gpu/grouped_conv3d_bwd_weight_scale/xdl/`
folders. The new .cpp files were also included in the `CMakeFiles.txt`
files of both folders.

## Test Plan

Execute `grouped_convnd_bwd_weight` tests to check execution on
different architectures.
The tests for bilinear and scale already include the tuple
`std::tuple<ck::half_t, ck::half_t, ck::half_t, ck::Number<3>>`, so in
principle, there is nothing to modify in the tests themselves.

## Test Result

`gfx1201`: Tests passed.
`gfx1100`: Tests passed.
`gfx90a`: Tests passed.
