BuildMenuOptions only when menu is opened

[vadimka123]

Very big performance issue: buildMenuOptions only when menu is opened
I'm have page with ~1000 selects with a ~1000 options. When render this page it takes ~ 40-50s and while page either hangs terribly or crashed. After this update page render takes 10s and there are no hangs. It's very need update.

Thanks @vadimka123 this is a very helpful change. Will be included in the next release.

For anyone having troubles updating from 2.4.4 to latest releases,

this looks like it could be a breaking change depending on how you interacted with the menu ( for example if your logic had a custom menu and a reference to it, your reference.current would now be null instead of your menu ref as it used to, which is indeed a breaking change )
