ASTERIXDB-1455: Scale CharRecord Buffer Expansions

Reading a 30 MB record requires > 1500 buffer reallocations when increasing by
a fixed amount.  Updated to scale up the buffer increases to reduce the number
of reallocations in case of large records.

> This should be updated to scale up the buffer increases to reduce the number of reallocations.
