Problem: Vim9: bool option type is number.
Solution: Have get_option_value() return a different value for bool and
number options. (closesvim/vim#7583)

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.
The main motivation for this is for the buf and win cases which need to
set up and restore context, and it's what specifically makes the
semantics of options nuanced, and thus this should not be repeated more
than once.
- nvim_get/set_option_value now share argument validation.
