Add option to prevent switching splits when executing e.g. RustLsp 'run'

Feature description

Whenever e.g. vim.cmd.RustLsp 'run' is executed, the focus changes to the newly open split with results.

I mitigate with with defer_fn. It's not pretty and it does not work when one has to e.g. select a testable (because of the timeout duration).

local function switch_to_previous_split()
  vim.defer_fn(function()
    vim.cmd 'wincmd w'
  end, 100)
end

vim.keymap.set('n', '<leader>x', function()
  vim.cmd.RustLsp 'run'
  switch_to_previous_split()
end, in_current_buffer.with_desc 'Rust run')

It would be nice to have an option like vim.cmd.RustLsp { 'run', pinned = true } to prevent focus changing.

hey 👋

the default termopen executor is very basic and doesn't have a lot of features.
If you want something more configurable, I recommend using the toggleterm executor (if you have toggleterm installed).
See :h rustaceanvim.config for details.
