Deprecate uncurried entrypoints and views

Motivation and Context

As part of v1, we are finally removing support for the 'old' entrypoints and views. We also discovered that it would be good to remove support for uncurried entrypoints and view.

Reasons for deprecation:

• 'Currification' of Ast_core means that uncurried syntax is rarely used
• It is now never idiomatic to use the uncurried version for entrypoints / views

Reasons against deprecation:

• Curried entrypoints/views could incur performance issues

Description

Refactors should_uncurry_{entry/view} to always uncurry entrypoints / views (thereby only permitting curried entrypoints / views).
