Support `auto_bucket` for numeric fields (ESQL-1494) This adds support for numeric fields to `auto_bucket` and adds a new `floor` function to round numeric down to the nearest integer. That function is exposed because it's probably useful. I added it in this PR because `auto_bucket` uses it as an implementation detail as well.

ESQL: Add `CEIL` function (#98847) Add the unary scalar function CEIL. Analogously to FLOOR, it rounds up its argument. - Implement CEIL, add it to the function registry and make sure it is serializable. - Add csv tests, unit tests and docs. - Add additional csv tests with different data types and some edge cases for both CEIL and FLOOR - Add unit tests and update docs for FLOOR.

NOTE: This is a noop for `long` (including unsigned) and `integer`.
For `double` this picks the the closest `double` value to the integer ala
