add methods to validate types, relations, ids and tuples

[rhamzeh]

Let's plan on moving this logic to language and have test cases for them, we can then implement this in several languages consistently

Current set of regexes used:

Protos:

• Type: https://github.com/openfga/api/blob/main/openfga/v1/openfga.proto#L19 | "^[^:#@\\s]{1,254}$"
• Relation: https://github.com/openfga/api/blob/main/openfga/v1/openfga.proto#L68 | "^[^:#@\\s]{1,50}$"
• Condition: https://github.com/openfga/api/blob/main/openfga/v1/openfga.proto#L39C16-L39C33 | "^[^\\s]{2,256}$"
• Object: https://github.com/openfga/api/blob/main/openfga/v1/openfga.proto#L80 | "^[^\\s]{2,256}$"

API:
https://github.com/openfga/openfga/blob/main/pkg/tuple/tuple.go#L35-L38

	userIDRegex   = regexp.MustCompile(`^[^:#\s]+$`)
	objectRegex   = regexp.MustCompile(`^[^:#\s]+:[^#:\s]+$`)
	userSetRegex  = regexp.MustCompile(`^[^:#\s]+:[^#\s]+#[^:#\s]+$`)
	relationRegex = regexp.MustCompile(`^[^:#@\s]+$`)

Validation has to pass both sets of regexes above in order to be valid according to the API.

On the VS Code/Playground side we use a different set of less permissive regexes:
https://github.com/openfga/vscode-ext/blob/07e65ccd3a0d533bcbbb2b4495899d73d2656e3b/server/src/openfga-yaml-schema.ts#L126-L154

We have yet more regexes in language:

language/pkg/js/validator/validate-dsl.ts

	const defaultTypeRule = "^[^:#@\\s]{1,254}$";
	// eslint-disable-next-line no-useless-escape
	const defaultRelationRule = "^[^:#@\\s]{1,50}$";
