IMPALA-14061: ADDENDUM - Fixed the JoinTranspose rule.

The JoinTranspose rule provided by Calcite was having 2 issues:

1) For tpcds-q10 and q35, an exception was being thrown. There is
a bug in the Calcite code when the Join-Project gets matched but
the Join is of reltype SemiJoin. In this case, the Projects do not
get created correctly and the exception gets thrown.

2) We only want to transpose a Project above a Join if there is an
underlying Join underneath the Project. The whole purpose is to
be able to create adjacent Join RelNodes. We do not have to tranpose
the Project when it is not sandwiched between two Join nodes. It is
preferable to keep it underneath the Join since the row width
calculation would be affected (the Project may reduce the number of
columns, thus reducing the row width).

This commit extends the given JoinProjectTranspose rule by Calcite
and handles these added restrictions.
