Avoid overflow when sorting missing last on epoch_millis datetime field

[msfroh]

Fixes #10253

Description

When sorting a datetime field with epoch_millis formatting and putting missing values last (with a descending sort) or first (with ascending sort), the datetime value is Long.MIN_VALUE.

When we try to render that, the formatter tries to emit the negative sign, followed by the absolute value of the original value. Since Long.MIN_VALUE = -Long.MAX_VALUE - 1, it is not possible to represent -Long.MIN_VALUE as a long.

To work around this, my proposed fix introduces an off-by-one error by truncating to Long.MAX_VALUE.
