Support for deparsing of ArrayCoerceExpr node in contrib/postgres_fdw

When using a prepared statement to select data from a PostgreSQL foreign
table (postgres_fdw) with the "field = ANY($1)" expression, the operation
is not pushed down when an implicit type case is applied, and a generic plan
is used.  This commit resolves the issue by supporting the push-down of
ArrayCoerceExpr, which is used in this case.  The support is quite
straightforward and similar to other nods, such as RelabelType.
