replace all instances of PERL_IMPLICIT_CONTEXT with MULTIPLICITY

Since the removal of PERL_OBJECT
(acfe0abcedaf592fb4b9cb69ce3468308ae99d91) PERL_IMPLICIT_CONTEXT and
MULTIPLICITY have been synonymous and they're being used interchangeably.

To simplify the code, this commit replaces all instances of
PERL_IMPLICIT_CONTEXT with MULTIPLICITY.

PERL_IMPLICIT_CONTEXT will stay defined for compatibility with XS
modules.
