Fix implicit usage of the current window-width in vtable.el

Previously, many functions in vtable.el called 'vtable--cache',
which computed 'vtable--cache-key' based on the current selected
window and frame; this could cause vtable functions to fail or
misbehave if they were not called from the selected window and
frame that 'vtable-insert' was last called in.

Now, the vtable cache is stored with the text of the vtable, so
that functions which need to interact with some vtable text can
do so reliably without having to use the same selected window
and frame.

Also, 'vtable-update-object' has always required TABLE to be
present at point in the current buffer; now its docstring states
this.
