Create synthetic exports symbol for commonjs module (#42655)
* Commonjs module:create synthetic exports symbol

Previously, the `module` identifier in commonjs modules got a synthetic
type with a single property `exports`. The exports property reused the
file's symbol, which, for a module file, gives the correct exported
properties.

However, the name of this symbol was still the filename of the file, not
`exports`. This PR creates a synthetic symbol for `exports` by copying
in a similar way to esModuleInterop's `default` symbol in
`resolveESModuleSymbol` (although the intent there is to strip off
signatures from the symbol).
