Add detail to the EXPLAIN EXTENDED output showing why a Map or Reduce task was

not vectorized" in addition to today's "Execution mode: vectorized".

EXPLAIN:
Execution mode: not vectorized
EXPLAIN EXTENDED:
Execution mode: not vectorized; detail: configuration variable
--hive.vectorized.execution.enabled is false
Execution mode: not vectorized; detail: data type not supported -- array<string>
Execution mode: not vectorized; detail: feature not supported -- PTF operator
Execution mode: not vectorized; detail: input format not supported --
org.apache.hadoop.mapred.TextInputFormat doesn't provide vectorized input
