Add query end marker

TypeQL query pipelines cannot be distinguished since query stages can be arbitrarily chained and concatenated. To resolve this, we introduce the end; marker. For example:
```
match ...
insert ...
end;
match ...
insert...
```
Is now correctly interpretable as two separate match-insert queries! Compared to before:
```
match ...
insert ...
match ...
insert ...
```
Where it was not clear if this is one match-insert-match-insert pipeline, two match-insert pipelines, or 4 separate queries, or anything in between!

For simplicity, any query can be terminated with an 'end;` marker, though it is redundant in for schema queries and 'fetch' queries:
```
define ...;
end; # redundant!
match ...
insert ...
end;  # not redundant!
match ...
insert ...
fetch { ... };
end;  # redundant!
```
Add prefix query parser

We create a "query prefix parsing" API, which attempts to parse the maximal query prefix from the input.

This is designed to help applications like Console consume a single complete query at a time from a set of concatenated queries.
Allow relates overrides to have lists

We fix one syntactic inconsistency, grammatically allowing list overrides for relation's roles:
```
define
  relation sub-rel, relates sub-role[] as super-role[];
```

Refactor grammar: partial rules, cleanup

We rename rules used for partial parsing to have suffix _partial rather than _no_test (randomized tests only use complete queries).
