Idan Horowitz f921952cc3 LibJSGCVerifier: Warn about missing visit_edges impls with GC members

Previously we would only warn about missing calls to visit inside
visit_edges implementations, now we warn as well when there's no
visit_edges implementation at all.

LibJSGCVerifier

This is a simple Clang tool to validate certain behavior relating to LibJS's GC. It currently validates two things:

For all types wrapped by GCPtr or NonnullGCPtr, that the wrapped type inherits from Cell
For all types not wrapped by GCPtr or NonnullGCPtr, that the wrapped type does not inherit from Cell (otherwise it should be wrapped).

This tool currently support being built with the Serenity Clang toolchain or the lagom Clang toolchain (in which case it won't be able to verify Serenity-only applications)

Building & Running with the Serenity toolchain

First build Serenity with the Clang toolchain for x86_64:

./Meta/serenity.sh build x86_64 Clang

Then build the tool with:

cmake -GNinja -B build
cmake --build build

Then run the tool with:

src/main.py -b <path to serenity>/Build

Building & Running with the Lagom toolchain

First build the Serenity lagom applications with:

./Meta/serenity.sh build lagom

Then build the tool with:

cmake -GNinja -DLAGOM_BUILD=ON -B build
cmake --build build

Then run the tool with:

src/main.py -l -b <path to serenity>/Build
