Fix cursor positioning on bidi boundaries

When the cursor is positioned between to script items that have different
writing directions, prioritise the script item that has the same direction
as the paragraph (i.e. the QTextEngine) when deciding where and how to
display the cursor. If visual cursor movement is enabled, the behavior is
unchanged.

As a drive-by, clean up coding style and avoid shadowing of function-
local variables.
