AK: Implement StringView::to_{lower,upper}case_string

Browse source 
This patch refactors StringImpl::to_{lower,upper}case to use the new
static methods StringImpl::create_{lower,upper}cased if they have to use
to create a new StringImpl. This allows implementing StringView's
to_{lower,upper}case_string using the same methods.

It also replaces the usage of hand-written to_ascii_lowercase() and
similar methods with those from CharacterTypes.h.
