Implement unnecessary bitmask on cast lint

[Francisco-Andre-Martins]

When downcasting from a large integer type (like u_64) to a smaller type (like u_8), the rust compiler
automatically truncates the integer adequately.
Still, some people do decide to perform a bitwise
and before casting, essentially truncating
the input before it is cast.

Closes #16125
