Initializing Bidi status members of InlineFlowBox

Initializing Bidi status members of InlineFlowBox

Valgrind complained of use before initialization so initializing
InlineFlowBox's m_lineBreakBidiStatusEor, m_lineBreakBidiStatusLastStrong,
and m_lineBreakBidiStatusLast to LeftToRight.

This code hasn't changed recently, I wonder why our valgrind bots don't see
that. My guess is that you're using a newer compiler that inlined more somehow.

I think that Valgrind has always been flakey with bitfields and can give false
positives - which this may be. Either way I don't think it hurts to initialize
to a sensible value since other members are also initialized.

thx for the review.
