Split common into composite subprojects with project references

- common/tsconfig.json is a solution root referencing layer tsconfigs
- Each layer has composite tsconfig with correct references and outDir
- Break buffer/services cycle via buffer-local service interfaces
- Move cell types, keyboard/unicode types, TaskQueue, and TerminalOptions
- Exclude *.test.ts from composite builds; fix parser IDisposable imports
