fix(api): nvim_set_option_value for global-local options

Browse Source 
global-local window options need to be handled specially. When `win` is
given but `scope` is not, then we want to set the local version of the
option but not the global one, therefore we need to force
`scope='local'`.

Note this does not apply to window-local only options (e.g. 'number')

Example:

   nvim_set_option_value('scrolloff', 10, {})       -- global-local window option; set global value
   nvim_set_option_value('scrolloff', 20, {win=0})  -- global-local window option; set local value
   nvim_set_option_value('number', true, {})        -- local window option

is now equivalent to:

   nvim_set_option_value('scrolloff', 10, {})
   nvim_set_option_value('scrolloff', 20, {win=0, scope='local'})  -- changed from before
   nvim_set_option_value('number', true, {win=0})                  -- unchanged from before

Only the global-local option with a `win` provided gets forced to local
scope.
