mu4e-{view,headers}: Refactor a (lamba) kbd-bound function into a named function 

Because this was a lambda C-h m would just show "??" instead of the
function name, and the documentation would be really confusing since it
showed the deparsed lambda function instead of the function name being
called.

Fix this by refactoring both the view & headers [ and ] functions into
named functions, and make their shared logic new internal
mu4u~{headers,view}-* functions.
