test(language-service): introduce new virtual testing environment (#39594) This commit adds new language service testing infrastructure which allows for in-memory testing. It solves a number of issues with the previous testing infrastructure that relied on a single integration project across all of the tests, and also provides for much faster builds by using the compiler-cli's mock versions of @angular/core and @angular/common. A new `LanguageServiceTestEnvironment` class (conceptually mirroring the compiler-cli `NgtscTestEnvironment`) controls setup and execution of tests. The `FileSystem` abstraction is used to drive a `ts.server.ServerHost`, which backs the language service infrastructure. Since many language service tests revolve around the template, the API is currently optimized to spin up a "skeleton" project and then override its template for each test. The existing Quick Info tests (quick_info_spec.ts) were ported to the new infrastructure for validation. The tests were cleaned up a bit to remove unnecessary initializations as well as correct legitimate template errors which did not affect the test outcome, but caused additional validation of test correctness to fail. They still utilize a shared project with all fields required for each individual unit test, which is an anti-pattern, but new tests can now easily be written independently without relying on the shared project, which was extremely difficult previously. Future cleanup work might refactor these tests to be more independent. PR Close #39594

test(language-service): update compiler_spec to use the new testing env (#40679) This commit updates compiler_spec.ts in the Ivy LS suite to utilize the new testing environment which was introduced in the previous commit. Eventually all specs should be converted, but converting one right now helps ensure that the new testing env is working properly and able to support real tests. PR Close #40679
