Grid range filter - optimize SQL query when from === to

[Sekiphp]

Description (*)

Optimalize SQL query in grid, when you filter same values in range field (number range) + added some docs & type hints.

SQL before

SELECT `main_table`.* 
FROM `sometable` AS `main_table` 
WHERE (`sid` >= '31233' AND `sid` <= '31233') ORDER BY sid DESC LIMIT 20

SQL after

SELECT `main_table`.* 
FROM `sometable` AS `main_table` 
WHERE (`sid` = '31233') ORDER BY sid DESC LIMIT 20

Special thanks to: original idea from @midlan

Manual testing scenarios (*)

1. Put same values to from and to in grid and check SQL query

Interesting that MySQL didn't catch that to optimize.
