<!-- The PR description should answer 2 (maybe 3) important questions:
-->
### What
This allows object types to be used as arguments for comparison
operators. This is useful for Elasticsearch's `range` operator, which
allows passing an object like `{ gt: 1, lt: 100 }` to an `integer` field
in order to filter items that are greater than `1` and less than `100`.
This PR has the nice side effect of dropping the requirement to use
information from scalar `BooleanExpressionType`s in place of
`DataConnectorScalarTypes`, which we only required because we were not
looking up the comparable operator information in scalar boolean
expression types correctly.
<!-- What is this PR trying to accomplish (and why, if it's not
obvious)? -->
<!-- Consider: do we need to add a changelog entry? -->
### How
Previously, when using `ObjectBooleanExpressionType` and
`DataConnectorScalarRepresentation`, we had no information about the
argument types of comparison operators (ie, what values should I pass to
`_eq`?), and so inferred this by looking up the comparison operator in
the data connector schema, then looking for a
`DataConnectorScalarRepresentation` that tells us what OpenDD type that
maps to.
Now, with `BooleanExpressionType`, we have this information provided in
OpenDD itself:
```yaml
kind: BooleanExpressionType
version: v1
definition:
name: Int_comparison_exp
operand:
scalar:
type: Int
comparisonOperators:
- name: _eq
argumentType: Int! # This is an OpenDD type
- name: _within
argumentType: WithinInput!
- name: _in
argumentType: "[Int!]!"
```
Now we look up this information properly, as well as tightening up some
validation around relationships that was making us fall back to the old
way of doing things where the user had failed to provide a
`comparableRelationship` entry.
This means
a) we can actually use object types as comparable operator types
b) scalar boolean expression types aren't used outside the world of
boolean expressions, which is a lot easier to reason about.

steps)? -->
