Link to Github Issue #18703

Problem description

In binary_ng, we are processing onetile per CB for (rd/wr/math). This value can be passed as compile-time arg to the kernels instead of being defined in each kernel. Later if this changes to be a dynamic value, decided by split_work API, we can pass this arg as a runtime-arg to the kernels

What's changed

• passed num tiles processed by CBs and DST as a compile-time argument
• move tile_reg api's out of loop to maintain sync between the tile_reg api's
