Replace vim.opt with vim.o (#1495)

* Replace vim.opt with vim.o

Because it offers a nicer interface and info on hover.
For now leave vim.opt when using the table interface (until vim.o
with tables is implemented)

* Add type hint for vim.opt.rtp

* Add a comment about using vim.opt instead of vim.o
