Issue #5845

Make watchpoint registration faster

Remove smoke test for xtend plugin

This commit adds support for aligning a platform to a forced

version using a constraint. Similarly to the dependency case,

this allows forcing the platform, but also implies that the

members of the platform are _also_ forced.

tag= is not supported, only tags= is

Previously, the buildscript lockfiles would potentially be overwritten

by the project ones if configurations happened to have the same name.

Fixes #5845

- prefer the plugins {} block

- disambiguate and unify conditionalLogic/don't

- remove unnecessary {} in GString
