[lldb] Fix block address resolution for functions in multiple sections (#137955)

Continuing the theme from #116777 and #124931, this patch ensures we
compute the correct address when a functions is spread across multiple
sections. Due to this, it's not sufficient to adjust the offset in the
section+offset pair (Address::Slide). We must actually slide the file
offset and then recompute the section using the result.

I found this out due to a failure to disassemble some parts of the
function, so I'm testing with that, although it's likely there are other
things that were broken due to this.
