[Tablet Orders] Improve/abstract logic around how Notices are displayed

[iamgabrielma]

From https://github.com/woocommerce/woocommerce-ios/pull/12325#pullrequestreview-1949566434

[...] needs to be more declarative. The viewModel, via its view, should say "put a notice up", and then the system should (probably) put that atop everything else.

At the moment Notices carry certain complexity around how and when are displayed, specially on Tablets, where notices may display incorrectly depending on the case unless handled specifically (or not on top of existing views). Ideally the framework should tackle these automatically upon state changes.
