Fix S6964 FP: Don't raise on properties annotated with the BindRequiredAttribute

[PaulBol]

Description

S6964 complains about under-posting when properties are not nullable and annotated with BindRequiredAttribute.

Indicates that a property is required for model binding. When applied to a property, the model binding system requires a value for that property.

Repro steps

Use view model with property

[BindRequired] public int PasswordMinLength { get; init; }

Expected behavior

No issue reported.

Actual behavior

S6964 issue reported.

Known workarounds

Use required keyword in addition. Needs further code changes.
