Fix reading fixed_len_byte_array of length 9-16 in parquet

[v-jizhang]

Cherry-pick of https://github.com/trinodb/trino/pull/9971 If the extra bytes are all zeros or all -1 for negative values, then the remaining bytes can be decoded as a short decimal.

Currently incorrect results are returned when a negative value is stored in fixed_len_byte_array of size 9-16 and read as a short decimal.
