gayyappan fffd6c2350 Use plpgsql procedure for executing compression policy ...

This PR removes the C code that executes the compression
policy. Instead we use a PL/pgSQL procedure to execute
the policy.

PG13.4 and PG12.8 introduced some changes
that require PortalContexts while executing transactions.
The compression policy procedure compresses chunks in
multiple transactions. We have seen some issues with snapshots
and portal management in the policy code (due to the
PG13.4 code changes). SPI API has transaction-portal management
code. However, the compression policy code does not use SPI
interfaces. But it is fairly easy to just convert this into
a PL/pgSQL procedure (which calls SPI) rather than replicating
portal managment code in C to manage multiple txns in the
compression policy.

This PR also disallows decompress_chunk, compress_chunk and
recompress_chunk in txn read only mode.

Fixes #3656
