Style disassembly in the TUI

This patch changes the TUI disassembly window to style its contents.
The styling should be identical to what is seen in the CLI.  This
involved a bit of rearrangement, so that the source and disassembly
windows could share both the copy_source_line utility function, and
the ability to react to changes in "set style enabled".

This version introduces a new function to strip the styling from the
address string when computing the length.  As a byproduct, it also
removes the unused "insn_size" computation from
tui_disasm_window::set_contents.
