GH-36931: [C++] Add cumulative_mean function (#36932)
6e6e6f0 
### Rationale for this change

Add `cumulative_mean` function

### What changes are included in this PR?

Implement `cumulative_mean` function. The current cumulative_* kernel generator can only be based on a simple binary arithmetic op and the state can only be a single value. I refactored it to using of a generic state such that it can handle complex operations such as `mean`, `median`, `var` etc.

### Are these changes tested?

Yes

### Are there any user-facing changes?
No

* Closes: #36931
