[PATCH 03/19] qapi/schema: name QAPISchemaInclude entities

[John Snow]

It simplifies typing to mandate that entities will always have a name;
to achieve this we can occasionally assign an internal name. This
alleviates errors such as:

qapi/schema.py:287: error: Argument 1 to "__init__" of
"QAPISchemaEntity" has incompatible type "None"; expected "str"
[arg-type]

Trying to fix it the other way by allowing entities to only have
optional names opens up a nightmare portal of whackamole to try and
audit that every other pathway doesn't actually pass a None name when we
expect it to; this is the simpler direction of consitifying the typing.
