* add GetWorkSpaceSize to base arg and make an example on convnd_bwd_weight * add bwd weight for bf16: init * remove redundant compute * use datatype and split k to check whether a workspace is used * remove unused computation for work space size * add some code for bfp16 * add device/grid unary op * add unary type convert to bwd-weight example * support bf16 splitk kernel for convnd bwd weight * 1. remove comments. 2. add checkvalidity. 3. add gridsize computation * add workspace size check * fix format * change function name

Caveat
Kernel Timing and Verification
CK's own kernel timer will warn up kernel once, and then run it multiple times to get average kernel time. For some kernels that use atomic add, this will cause output buffer to be accumulated multiple times, causing verfication failure. To work around it, do not use CK's own timer and do verification at the same time. CK's own timer and verification in each example and ckProfiler can be enabled or disabled from command line.
