AutoSize TextView (part 11) - fix final APIs

* public attr "autoSizeText" becomes "autoSizeTextType"
  (inlined with all other methods and naming)
* documentation for autoSizetextType "uniform" re-worked:
  "The TextView scales text size both horizontally and
  vertically to fit  within the container"
* converted comments into Javadoc for
  TextView#AUTO_SIZE_TEXT_TYPE_NONE and
  TextView#AUTO_SIZE_TEXT_TYPE_UNIFORM
* better documented attr "autoSizePresetSizes" to specify
  it is a resource array of dimensions
* various small fixes in comments
