Grails Bom inconsistently applied

[jdaugherty]

The grails bom appears to be inconsistently applied when using a project with buildSrc. To get buildSrc to work, you have to:

1. add implementation platform("org.grails:grails-bom:$grailsVersion") or implementation"org.grails:grails-bom:$grailsVersion" to buildSrc/build.gradle
2. add the same to the project's build.gradle

This may only be an issue on projects with buildSrc. We saw this in grails-views & grails-redis. Views fixed this by excluding the bom, but redis fixed it by adding the above. What's worse, is this behavior is inconsistent.

Spring Dependency Management Gradle Plugin vs Gradle Platforms - need to standardize on one or the other

spring-gradle-plugins/dependency-management-plugin#211
vs.
https://docs.gradle.org/current/userguide/platforms.html

grails-bom is being applied twice

spring-boot-dependencies applied more than once - spring-boot plugin may be part of this

grails-gradle-plugin is currently auto applying grails-bom via the Spring Dependency Management Gradle Plugin
