refactor(ts): remove op_cache (#5071)

This PR removes op_cache and refactors how Deno interacts with TS compiler.

Ultimate goal is to completely sandbox TS compiler worker; it should operate on
simple request -> response basis. With this commit TS compiler no longer
caches compiled sources as they are generated but rather collects all sources
and sends them back to Rust when compilation is done.

Additionally "Diagnostic" and its children got refactored to use "Deserialize" trait
instead of manually implementing JSON deserialization.
