121c940ace Teach TRAP writer to truncate strings longer than 1MiB. 
The evaluator cannot in general handle strings that are longer than 1MiB when UTF8-encoded. Similar to other extractors, we now truncate such strings to fit within the size limit.

46c4670796 Make HardcodedCredentials query less noisy. 
Considering "cert" and "account" to be sensitive leads to a massive number of false positives, especially on cockroach and kubernetes.

7bc68c4302 Adapt Go tests to codeql test 
These changes make the tests work with the coming `codeql test` support.

The `queries.xml` file defines which extractor the `codeql test`
runner will use to extract databases for the tests. In the future one
will be able to write this information in `qlpack.yml`, but we can't
do that immediately because the _existing_ CodeQL tooling would refuse
to parse a `qlpack.yml` that has the new field in it.

f4a24b0353 Improve type information for tuple elements. 
We would previously rely on the type information of the target variable into which the element is stored, but that could be a more general type.

For example, in the assignment

```go
x, y := f()
```

the type of `x` might be an interface while the type of `f()[0]` is a concrete type implementing that interface.

ee723d8a4f Fix DeadStoreOfField false positive. 
We should look into properly desugaring embedded types in the IR, but for now this workaround should suffice.
