Enable removal of blank line following topmost package statement

Discussed in #3629

I've attempted to configure scalafmt to remove all newlines (including, pertinently, the one added between the topmost package statement and the next statement). Sadly, I've come up short. Prior discussion suggests that this is desired broadly. I suspect I'm in the minority.

Nonetheless, I'm curious. Is this already possible? If not, could it be made configurable?

Ideally, this code:

package org.scalafmt

import scala.collection.Map

Could be automatically formatted as follows:

package org.scalafmt
import scala.collection.Map

Re-posting from the discussion, this configuration is insufficient to achieve the desired formatting:

newlines {
  topLevelBodyIfMinStatements = []
  topLevelBodyMinStatements = 0
  topLevelStatementBlankLines = [{ blanks = -1 }]
}
runner.dialect = scala3
version = 3.7.14

One workaround that can be leveraged is to nest top-level statements:

package org.scalafmt:
  object A

It's not ideal, but it does work.
