qapi: Test use of 'number' within alternates

Browse source 
Add some testsuite exposure for use of a 'number' as part of
an alternate.  The current state of the tree has a few bugs
exposed by this: our input parser depends on the ordering of
how the qapi schema declared the alternate, and the parser
does not accept integers for a 'number' in an alternate even
though it does for numbers outside of an alternate.

Mixing 'int' and 'number' in the same alternate is unusual,
since both are supplied by json-numbers, but there does not
seem to be a technical reason to forbid it given that our
json lexer distinguishes between json-numbers that can be
represented as an int vs. those that cannot.

Improve the existing test_visitor_in_alternate() to match the
style of the new test_visitor_in_alternate_number(), and to
ensure full coverage of all possible qtype parsing.
