[Feat] (MG_Impl): implement glCreateQueries and stop treating a reserved name as a query

Browse Source 
glGenQueries only reserves names; a name becomes a query object when it is first
used with BeginQuery or QueryCounter (GL 4.6 core 4.2.1). MobileGL created the
live object eagerly at glGenQueries time and glIsQuery reported every reserved
name as an object, with a comment noting the shortcut.

The registry already distinguished the two states -- a target of 0 means the name
has never been used -- so glIsQuery now consults it, and a name that came from
glCreateQueries carries a flag saying it is an object regardless.

glCreateQueries itself was a stub. It creates the objects outright with their
target already fixed, which is the whole point of the DSA form: there is no
binding step to infer the target from later.
