Minor cleanup of the BRIN parallel build code
Commit b437571714 added support for parallel builds for BRIN indexes,
using code similar to BTREE parallel builds, and also a new tuplesort
variant. This commit simplifies the new code in two ways:
* The "spool" grouping tuplesort and the heap/index is not necessary.
The heap/index are available as separate arguments, causing confusion.
So remove the spool, and use the tuplesort directly.
* The new tuplesort variant does not need the heap/index, as it sorts
simply by the range block number, without accessing the tuple data.
So simplify that too.
Initial report and patch by Ranier Vilela, further cleanup by me.
