### Description
Moves the gradle task definition for `code_format_checks` up into
`code-formatting.gradle`, which all the modules apply
from. This should ensure when CI executes `./gradlew
code_format_checks`, all modules are checked for code formatting
violations.

### Steps to test this PR

- [x] It is expected the checks will fail until
#2888 is merged, so let's
merge that first 🛑
- [ ] Once PR above is merged, Run `./gradlew code_format_checks`;
verify it passes
- [ ] Add a deliberate code format violation to any module (e.g., add an
extra space character to a function's parameter)
- [ ] Run `./gradlew code_format_checks`; verify it fails
