REVISION SUMMARY
  this is entirely the same kind of change as done in
  c695aa5a21a731ab72c8405141b43feccad2b56a <https://phabricator.kde.org/R236:c695aa5a21a731ab72c8405141b43feccad2b56a>
  
  a proxy does not automatically adopt the same focus policy as the widget
  it proxies. instead it has its own policy which is simply the qwidget
  default.
  this prevents keyboard focus from working in (e.g.) buddy scenarios as well
  as when hitting Tab to move through the intractable widgets with a
  keyboard.
  seeing as kpasswordlineedit is essentially a lineedit and being able to
  "tab" from a username edit to a password edit seems a crucial behavioral
  expectation.
  
  BUG: 398275
  CHANGELOG: KPasswordLineEdit now correctly inherits its QLineEdit's focusPolicy

TEST PLAN
  designer reports StrongFocus as default now. when using the KPLE without changing its policy it will correctly receive focus through keyboard tabbing
