[fix](function) MicroSecondsSub without scale (apache#38945)
## Proposed changes Added the computeSignature function for millisecond/microsecond calculation functions to generate parameters and return values with the appropriate precision. Modified the microSecondsAdd function, which was used for constant folding, because constant folding uses the precision of the parameters for calculation. However, for millisecond/microsecond calculations, it is necessary to set the precision to the maximum to ensure correct display. before ``` mysql> SELECT MICROSECONDS_SUB('2010-11-30 23:50:50', 2); +-------------------------------------------------------------------+ | microseconds_sub(cast('2010-11-30 23:50:50' as DATETIMEV2(0)), 2) | +-------------------------------------------------------------------+ | 2010-11-30 23:50:49 | +-------------------------------------------------------------------+ ``` now ``` mysql> SELECT MICROSECONDS_SUB('2010-11-30 23:50:50', 2); +-------------------------------------------------------------------+ | microseconds_sub(cast('2010-11-30 23:50:50' as DATETIMEV2(0)), 2) | +-------------------------------------------------------------------+ | 2010-11-30 23:50:49.999998 | +-------------------------------------------------------------------+ ``` <!--Describe your changes.-->
