fix(termcap): use tmux passthrough sequence when running in tmux (#26281)

Browse Source 
tmux intercepts and ignores XTGETTCAP so wrap the query in the tmux
passthrough sequence to make sure the query arrives at the "host"
terminal.

Users must still set the 'allow-passthrough' option in their tmux.conf.
