MCOL-4177 Add support for bulk insertion for wide decimals.

Browse Source 
1. This patch adds support for wide decimals with/without scale
     to cpimport. In addition, INSERT ... SELECT and LDI are also
     now supported.
  2. Logic to compute the number of bytes to convert a binary
     representation in the buffer to a narrow decimal is also
     simplified.
