I have added an additional variable to allow users to customise the value of the blur property for box-shadows. Previously, input shadows set their own blur value, which made it difficult to overwrite due to the usage of mixins to generate a lot of the validation styles; Issue #31940.
This PR offers a new $input-btn-focus-blur variable, which defaults to a value of 0, and is then used to populate the blur for all input related box-shadow variables.
