typescript program has invalid imports.

[iwahbe]

This was discovered compiling our program generator tests. We generate the import statement import * from "fs";. This should be import * as fs from "fs";.

Steps to reproduce

1. cd pkg/codegen
2. tsc --noEmit internal/test/testdata/aws-s3-folder-pp/aws-s3-folder.ts
   Note: this path is only valid after iwahbe/7802/compile program generator test output #8036 lands. Before that, the file can be found in internal/test/testdata
   Expected: Clean compile
   Actual:

internal/test/testdata/aws-s3-folder-pp/aws-s3-folder.ts(3,10): error TS1005: 'as' expected.
internal/test/testdata/aws-s3-folder-pp/aws-s3-folder.ts(3,15): error TS1005: 'from' expected.
internal/test/testdata/aws-s3-folder-pp/aws-s3-folder.ts(12,73): error TS1005: ';' expected.
internal/test/testdata/aws-s3-folder-pp/aws-s3-folder.ts(17,29): error TS1005: '{' expected.
internal/test/testdata/aws-s3-folder-pp/aws-s3-folder.ts(17,108): error TS1005: ';' expected.

This looks like it has since been fixed. Test is reenabled in #11478.
