[FEATURE] Filters for hooks

[Stranger6667]

Continuation of #1673

Extend the hook system to allow users to specify the scope of hook functions through a decorator instead of implementing conditions inside the hook function body. This would simplify the filtering process and make it easier to use.

# Filter via custom function
def select_operations(context):
    # Or any complex logic here
    return context.operation.method == "PATCH" and context.operation.path == "/users/{user_id}/"
    

# Apply hook only if `select_operations` returned `True`
@schemathesis.hook.apply_to(select_operations)
def filter_query(context, query):
    return query["key"] != "42"


# Apply hook to everything except `GET /users/{user_id}/`
@schemathesis.hook.skip_for(method="GET", path="/users/{user_id}/")
def map_path_parameters(context, path_parameters):
    path_parameters["user_id"] = 42
    return path_parameters


# Simple filter hook for all operations
@schemathesis.hook
def filter_query(context, query):
    return query["key"] != "42"
