numeric.c, complex.c: Add finite? and infinite? consistent with Float
* numeric.c (num_finite_p, num_infinite_p): Add Numeric#finite? and
Numeric#infinite? [Feature #12039] [ruby-core:73618]
* complex.c (rb_complex_finite_p): Add Complex#finite?
* complex.c (rb_complex_infinite_p): Add Complex#infinite?
* test/ruby/test_bignum.rb: Add test for Integer#finite? and
Integer#infinite?
* test/ruby/test_fixnum.rb: ditto.
* test/ruby/test_rational.rb: Add test for Rational#finite? and
Rational#infinite?
* test/ruby/test_complex.rb: Add test for Complex#finite? and
Complex#infinite?
