common/*: update pages of some POSIX special built-in utilities (#11956)

Browse Source 
* exec, export, readonly, set, shift, trap: replace command descriptions

* exec, exit, export, readonly, set, shift, trap, exec, export: replace example descriptions

* exec, trap: replace "More information" links

* trap: remove prefix "SIG" from some command arguments

Although POSIX allows implementations to specify signal names without
the prefix "SIG", I will choose the most portable form.

* export: replace term
