ESQL: Document BUCKET as a grouping function (#107864) This adds the documentation for BUCKET as a grouping function and the addition of the "direct" invocation mode providing a span (in addition to the auto mode).

ESQL: AVG aggregation tests and ignore complex surrogates (#110579) Some work around aggregation tests, with AVG as an example: - Added tests and autogenerated docs for AVG - As AVG uses "complex" surrogates (A combination of functions), we can't trivially execute them without a complete plan. As I'm not sure it's worth it for most aggregations, I'm skipping those cases for now, as to avoid blocking other aggs tests. The bad side effect of skipping those tests is that most tests in AvgTests are actually ignored (74 of 100)

ESQL: Fix Max doubles bug with negatives and add tests for Max and Min (#110586) `MAX()` currently doesn't work with doubles smaller than `Double.MIN_VALUE` (Note that `Double.MIN_VALUE` returns the smallest non-zero positive, not the smallest double). This PR adds tests for Max and Min, and fixes the bug (Detected by the tests). Also, as the tests now generate the docs, replaced the old docs with the generated ones, and updated the Max&Min examples.

Added Percentile aggregation tests and Kibana docs (#111050) - Added Percentile aggregation tests and autogen docs - Added a new "appendix" section to FunctionInfo. Existing Percentile docs had a final, long section with info, and we need this to leep it. We have an "detailedDescription" attribute already, but it's right after the description, and it would make it harder to read the important bits of the function (types, examples...). So I'm not reusing it.

After completion, the test can be uncommented and everything should work fine
