AAPT2: Reformatted dump command invocations

Use with:
  aapt2 dump apc [apc]
  aapt2 dump configurations [apk]
  aapt2 dump strings [apk]
  aapt2 dump resources [apk]
  aapt2 dump xmlstrings [apk] --file [file]
  aapt2 dump xmltree [apk] --file [file]

Will add permissions and badging in a later commit.

Bug: 73351292
Test: Manual tests of the commands
