This change adds the missing switch statement in
CodegenReadScalar() for AVRO_DECIMAL so that we will
also codegen if an avro table contains AVRO_DECIMAL.
With this change, the following query improves by 37.5%,
going from 8s to 5s:
select count(distinct l_linenumber), avg(l_extendedprice), max(l_discount), min(l_tax) from tpch15_avro.lineitem;
This change also un-inlines BitUtil::ByteSwap() as the
third argument 'len' is not compilation constant for
all call sites.
