Add macro RelationIsPermanent() to report relation permanence

Browse Source 
Previously, to check relation permanence, the Relation's Form_pg_class
structure member relpersistence was compared to the value
RELPERSISTENCE_PERMANENT ("p"). This commit adds the macro
RelationIsPermanent() and is used in appropirate places to simplify the
code.  This matches other RelationIs* macros.

This macro will be used in more places in future cluster file encryption
patches.
