**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** <!-- A clear and concise description of what the problem is. Ex. I'm always frustrated when [...] (This section helps Arrow developers understand the context and *why* for this feature, in addition to the *what*) --> Currently the decimal conversion kernels perform unnecessary checks, this predates https://github.com/apache/arrow-rs/pull/6836 although is made worse by this PR. In particular when performing a decimal conversion between the same decimal primitive (i.e. Decimal128 vs Decimal256) it should be able to elide both the checks in `O::Native::from_decimal` and `O::validate_decimal_precision`. This in turn would allow using the infallible `unary` kernel, likely yielding significant performance improvements. **Describe the solution you'd like** <!-- A clear and concise description of what you want to happen. --> **Describe alternatives you've considered** <!-- A clear and concise description of any alternative solutions or features you've considered. --> **Additional context** <!-- Add any other context or screenshots about the feature request here. --> -- This is an automated message from the Apache Git Service.
