fix(clipboard): enable cache for function providers #34470

Browse Source 
Problem:
With these settings, copy/pasting `blockwise-visual` (with `CTRL+V`)
incorrectly pastes as a `linewise` mode because `regtype` is ignored:

    vim.opt.clipboard = 'unnamedplus'
    vim.g.clipboard = 'osc52'

To reproduce: press `CTRL+V` and select some characters press `p` and
observe that it is pasted in `linewise` mode.

Solution:
Enable the [clipboard.vim](https://github.com/neovim/neovim/blob/master/runtime/autoload/provider/clipboard.vim#L281-L283))
cache for function providers, so that `regtype` is maintained for the OSC52
clipboard provider.
