Disallow registration of types beginning with lowercase letters
Allowing types with lowercase names causes ambiguity, as can be seen in
QTBUG-43567 and the comment in IRBuilder::visit(), which explains that
"the grammar can't distinguish between two different definitions" whose
only difference is casing of the first letter.
- Prevent registration (return -1 with e.g. qmlRegisterType()) when a
type name doesn't begin with an uppercase letter.
- Document the uppercase type name rule in more places.
