Currently `readConfiguration` relies on the file system to perform disk utilities needed to read determine a project configuration file and read it. This poses a challenge for the language service, which would like to use `readConfiguration` to watch and read configurations dependent on extended tsconfigs (#39134). Challenges are at least twofold: 1. To test this, the langauge service would need to provide to the compiler a mock file system. 2. The language service uses file system utilities primarily through TypeScript's `Project` abstraction. In general this should correspond to the underlying file system, but it may differ and it is better to go through one channel when possible. This patch alleviates the concern by directly providing to the compiler a "ParseConfigurationHost" with read-only "file system"-like utilties. For the language service, this host is derived from the project owned by the language service.
