style(compat-eslint): unify typescript import to namespace form

`lib/ts-scope-manager.ts` was the only file using
`import ts = require('typescript')` while the other three lib
files used `import * as ts from 'typescript'`. Both forms work
for the `export = ts` shape under `module: Node16`, but `ts` is
only ever used as a namespace (`ts.SyntaxKind`, `ts.factory`,
etc.) — `import * as` reads more naturally for that.

The remaining `import = require` (`CodePathAnalyzer`) stays as is
— CPA is used as a constructor, not a namespace, so the bare-
value form is the right shape there.
