Add CommandExecutionTests (Java and Kotlin and DSL)

Addresses todo in CommandAPI@62d5ea5 on `dev/command-build-rewrite`

Made `MockPlatform` respect `forceNative` parameter of `getSenderForCommand` (Copied from 9cf533d and partially from 24692f8)

Expand testing framework to work for all sender types
