Update tsc-instrumented for project build (#45383)

* Update tsc-instrumented for project build

loggedIO has a weird build that never got updated for the project build
system. This PR just adds a project for it in a straightforward way. It
might be less efficient than the old way, but that's not a big concern
for recording RWC test cases.

However, I may have done things wrong. If anybody knows
tsc-instrumented, please comment.

* Create a second loggedIO tsconfig for tsc-instrumented

The normal tsconfig should not have `prepend`; the standalone one for
tsc-instrumented should.

* fix semicolon lint
