feat(junit): replace OptionsFactory with @PlaywrightOptions annotation

[Yury Semikhatsky (yury-s)]

Summary

• Fixture options are now provided by fields or methods of the test class annotated with @PlaywrightOptions, the way Spring, Micronaut and Testcontainers configure tests. A non-static member is read per test instance, so options can depend on injected fields such as an embedded server's URL.
• A member can be of type Options, or of type BrowserType.LaunchOptions, Browser.NewContextOptions or APIRequest.NewContextOptions to override just that layer; a @Nested class can override options for its tests.
• OptionsFactory and UsePlaywright.value() are removed; the API is experimental.
• Supersedes feat(junit): allow OptionsFactory to access test instance fields #2008.

Fixes #1881
