cmGlobalNinjaGenerator: Teach WriteBuild about implicit outputs

Ninja 1.7 introduced support for implicit outputs on build statements.
Teach WriteBuild to generate the corresponding syntax.  Leave it up to
callers to decide whether implicit outputs are supported by the Ninja
version in use.  For now simply update all call sites to pass an empty
list of implicit outputs.
