[SPARK-51555][SQL] Add the time_diff() function
### What changes were proposed in this pull request?
Implement the `time_diff` function, which returns the difference between
two times measured in units.
Syntax
```
time_diff(unit, start, end)
unit
{ MICROSECOND |
MILLISECOND |
SECOND |
MINUTE |
HOUR }
```
Arguments
- `unit`: A unit of measure.
- `start`: A starting TIME expression.
- `end`: An ending TIME expression.
Returns
An INTEGER.
If start is greater than end the result is negative.
### Why are the changes needed?
Users will be able to calculate time difference in specified units.
### Does this PR introduce _any_ user-facing change?
Yes, this PR introduces a new expression.
### How was this patch tested?
New unit tests for time truncation, catalyst expression level unit tests
with & without codegen, e2e SQL tests / golden files in both ANSI and non-ANSI
modes.
### Was this patch authored or co-authored using generative AI tooling?
No.
Closes #51715 from uros-db/timediff.
