Allow statement ordering in blocks

[drawers]

Another common site for merge conflicts and disorder are blocks like the dependencies { block in a build.gradle.kts file.

We could make @Alphabetical apply to a block:

@Alphabetical run {
    println("apple")
    println("banana")
}

in which case, it would scan the lines of the block and enforce dictionary order. This could be a "nuclear option" where none of the other annotation targets make sense.
