feat(developer): add a builder-supports test for builder scripts

We could do something like:

```bash
if [[ ./build.sh builder-supports --option ]]; then
if [[ ./build.sh builder-supports action ]]; then
if [[ ./build.sh builder-supports :target ]]; then
```

This would allow us to more easily switch build parameters in build configurations, and is cleaner than using:

```bash
if [[ `./build.sh --help | grep -- --option` ]]; then
if [[ `./build.sh --help | grep -- action` ]]; then
if [[ `./build.sh --help | grep -- :target` ]]; then
```
