fix(util.toggle): correctly toggle inlay_hints (#3202)

`is_enabled` also accepts a `filter` and when we initially toggle
`inlay_hints` on
[here](735f5905f8/lua/lazyvim/plugins/lsp/init.lua (L153)),
we pass a `bufnr` which sets the `inlay_hints` in the `bufstate` (see
[here](42aa69b076/runtime/lua/vim/lsp/inlay_hint.lua (L407-L432))),
but when we call `is_enabled` without a filter table the returned result
if from the `globalstate` (see
  [here](42aa69b076/runtime/lua/vim/lsp/inlay_hint.lua (L376-L388))).
