22a3fccf79 Use type to hint that constraining to embedded fields is a good first step
This improves the join order for `implicitFieldSelection`

e1b4867a19 Refactor embedded field calculation to expose access chain
This allows us to reuse the embedded field calculation in the
logic for generating implicit field selection nodes.

13cd19ee40 Make ImplicitFieldReadInstruction include implicit deref when needed
When an ImplicitFieldReadInstruction reads an embedded field which has
a pointer type, it now includes the implicit dereference.

It might be better to extend MkImplicitDeref to cover this case, so we have
an explicit instruction for this. Then it would be easier to see when
dereferences are happening, and hence when they might cause a nil pointer
dereference.

2d3caf48c1 Add implicit field reads for promoted fields
This may not work when the embedded fields are pointer types, as
we don't have anything corresponding to MkImplicitDeref

b6dddd36e1 Update FieldTarget.getBaseType()
It wasn't defined when `getBase()` was an EvalImplicitDerefInstruction.
Rewriting it like this means it should work no matter what type of
instruction `getBase()` is.

23b8af3a56 Tolerate empty-string CODEQL_PLATFORM
This is normal when invoked with tracing disabled, so we also don't log when this happens.

c2c88b0835 Unify two implementations of GetExtractorPath
This retains both their features:
* The new util.go one cached its result.
* The old go-autobuilder.go one worked under ODASA, where CODEQL_GO_EXTRACTOR_ROOT is unset but os.Executable is a useful substitute.
