Update QString::isRightToLeft() to take directional hints into account
Make sure we properly handle both directional embeddings as well as
directional isolates to determine the direction of the string.
According to the latest version of the Unicode bidi algorithm,
parts of the string contained inside an directional isolate is
to be ignored when determining the paragraph direction. Embedding
markers themselves are to be ignored as well, but not the characters
inside an explicit directional embedding or override.
This is also some required pre-work to get our BiDi algorithm
updated to the latest version of the standard.
Move the implementation to QStringView and implement the methods
in QString and QStringRef through that implementation.
