[CK] Small improvements for grouped conv backward weight
 (#4872)

## Motivation

Improvements for CK Tile convolution builder run function and atol/rtol
calculations.

## Technical Details

- Add preprocessing function for wrw when k_batch is larger than 1 for
builder run function
- Divide num acums by number of groups to get real number of accums

## Test Plan

CI wrw tests

## Test Result

pending
