[NFC] Remove TSCBasic.InMemoryFileSystem dependency (#7484)

### Motivation:

As we'd like to quickly iterate on asyncification of our file system
code and since TSC package is deprecated we should reduce our number of
dependencies on it.

### Modifications:

Removed `import class TSCBasic.InMemoryFileSystem` statements.

### Result:

We have less dependencies on the TSC package.
