[fix](parquet)Fix the be core issue when reading parquet unsigned types. (#39926)
bp #39926
Proposed changes
Since Doris does not have an unsigned type, we convert parquet uint32 type to doris bigint (int64) type. When reading the parquet file, the byte size stored in parquet and the byte size of the data type mapped by doris are inconsistent, resulting in be core. Fix: When reading, we read according to the byte size stored in parquet, and then convert it to the data type mapped by doris.
Mapping relationship description:
parquet -> doris
UInt8 -> Int16
UInt16 -> Int32
UInt32 -> Int64
UInt64 -> Int128.
