@ishaan812 `age_prepare_string` is meant to be called by a driver or
something passing `cstrings`.
```
CREATE FUNCTION ag_catalog.age_prepare_cypher(cstring, cstring)
RETURNS boolean
LANGUAGE c
STABLE
PARALLEL SAFE
AS 'MODULE_PATHNAME';
```
```

Add the ability to pass parameters to the cypher function
Added the ability to pass parameters to the cypher() function via
a function called age_prepare_cypher().
This extra function is necessary because the cypher() function itself
isn't actually executed - it is instead transformed and replaced. This
means that it needs to have its input parameters resolved prior to
that transform. However, parameters aren't resolved until the
execution phase. So, another command to resolve them needs to run
prior to the cypher() function call.
This mainly impacts the drivers, which will need to be updated.
Additionally, modified the golang driver as an example of this new
usage.
Added regression tests.
