Commit ef796639451af63bc9f4dbdc2a79bfc2f5048a93 in impala's branch

IMPALA-8840: Check failed: num_bytes <= sizeof(T) (5 vs. 4)
The actual DCHECK failure was fixed by the change for IMPALA-8833.
Added a DCHECK to RleBatchDecoder so that it does not accept bit widths
higher than the width of its type parameter.
Also preventing UnpackAndDecodeValues from using higher bit widths than
32, the width of the dictionary index type, with a static assert. This
also reduces compile time because the compiler does not have to generate
code for invalid bit widths.
