refactor(multiple): remove coercion members (#24055)

* Replaces all usages of the `ngAcceptInputType` members with type declarations directly on the setters.
* Replaces the lint rule that was checking that the correct coercion members were added with a rule that doesn't allow new coercion members to be added.

 ```ts

 The above code allows users to set `disabled` similar to how it can be set on native inputs:
 ```html
 <component disabled></component>
 ```
-Even though an empty string is technically what is being provided as the value of `disabled`,
-`ngAcceptInputType` allows the mismatched type to be provided and `coerceBooleanProperty`
-interprets the given value (an empty string) to the correct type & value, which in this case would
-be `true`.
 
 #### Expose native inputs
 Native inputs used in components should be exposed to developers through `ng-content`. This allows
