1. Prevent parent window margins from being used in UI doc child frame. …

   When margins are used in the main window (such as Flymake/Flycheck
   diagnostic indicators in the margin instead of the fringe), causing
   `left-margin-width` and/or `right-margin-width` in the parent to be
   non-zero, the child frame was seeing those margins and text was being
   wrapped incorrectly.
   
   The child frame is sized to handle the amount of text on a line (up to
   `lsp-ui-doc-max-width`) and then `fill-region` is used to hard-wrap
   the text.  The computation of the size of the frame assumes there are
   no fringes or margins which consume part of this frame.  However, when
   the margin was visible in the child frame, it was causing text to be
   soft-wrapped prior to the hard-wrap.
   
   This change sets the margin sizes to 0 in the buffer of the child
   frame and then forces the window of the child frame to utilize these
   settings, preventing parent margins from being displayed in the child
   frame.
