Instantiate validators at definition time

Validators are now instantiated once at route definition time rather than per-request, eliminating repeated allocation overhead. Validator instances are frozen via `DeepFreeze` to make them safe for sharing across requests.

- Override `Validators::Base.new` to call `freeze` after initialization
- Add `Grape::Util::DeepFreeze` to recursively freeze Hash/Array/String values while leaving Procs, scopes, and coercers unfrozen
- Remove `ValidatorFactory` (no longer needed)
- Update all validators to be compatible with frozen instances (move any mutable state out of instance variables set at validation time)
- Add specs for `DeepFreeze`, `SameAsValidator`, and `ExceptValuesValidator`
