Cleanup 'ttym[ouse]', FEAT_MOUSE, mouse_(dec|gpm|etc.)

Because of 3baba1e7bc6698e6bc9f1d37fce88b30d6274bc9, it's dead code.

-							*xterm-mouse*
-	   xterm	xterm-like mouse handling.  The mouse generates
-			"<Esc>[Mscr", where "scr" is three bytes:
-				"s"  = button state
-				"c"  = column plus 33
-				"r"  = row plus 33
-			This only works up to 223 columns!  See "dec",
-			"urxvt", and "sgr" for solutions.
-	   xterm2	Works like "xterm", but with the xterm reporting the
-			mouse position while the mouse is dragged.  This works
-			much faster and more precise.  Your xterm must at
-			least at patchlevel 88 / XFree 3.3.3 for this to
-			work.  See below for how Vim detects this
-			automatically.
-							*netterm-mouse*
-	   netterm	NetTerm mouse handling.  The mouse generates
-			"<Esc>}r,c<CR>", where "r,c" are two decimal numbers
-			for the row and column.
-							*dec-mouse*
-	   dec		DEC terminal mouse handling.  The mouse generates a
-			rather complex sequence, starting with "<Esc>[".
-			This is also available for an Xterm, if it was
-			configured with "--enable-dec-locator".
-							*urxvt-mouse*
-	   urxvt	Mouse handling for the urxvt (rxvt-unicode) terminal.
-			The mouse works only if the terminal supports this
-			encoding style, but it does not have 223 columns limit
-			unlike "xterm" or "xterm2".
-							*sgr-mouse*
-	   sgr		Mouse handling for the terminal that emits SGR-styled
-			mouse reporting.  The mouse works even in columns
-			beyond 223.  This option is backward compatible with
-			"xterm2" because it can also decode "xterm2" style
-			mouse codes.

-	are recognized if enabled at compile time, and 'ttymouse' is not
-	"xterm", "xterm2", "urxvt" or "sgr" (because dec mouse codes conflict
-	with them).
-	This option is automatically set to "xterm", when the 'term' option is
-	set to a name that starts with "xterm", "mlterm", or "screen", and
-	'ttymouse' is not set already.
-	Additionally, if vim is compiled with the |+termresponse| feature and
-	|t_RV| is set to the escape sequence to request the xterm version
-	number, more intelligent detection process runs.
-	The "xterm2" value will be set if the xterm version is reported to be
-	from 95 to 276.  The "sgr" value will be set if the xterm version is
-	277 or highter.
