…stic#124594) This patch builds on the work in elastic#122999 and elastic#113757 to natively store array offsets for numeric fields instead of falling back to ignored source when `source_keep_mode: arrays`.

Fix and unmute testSynthesizeArrayRandomIgnoresMalformed (cherry picked from commit 2ff03ac) # Conflicts: # muted-tests.yml
Previously, when calculating the offsets, we just compared the values as-is without any loss of precision. However, when the values were saved into doc values and loaded in the doc values loader, they could have lost precision. This meant that values that were not duplicates when calculating the offsets could now be duplicates in the doc values loader. This interfered with the de-duplication logic, causing incorrect values to be returned. My solution is to apply the precision loss before calculating the offsets, so that both the offsets calculation and the SortedNumericDocValues de-duplication see the same values as duplicates. (cherry picked from commit db73175)
