build: remove check-env script (angular#39980)

Remove the check-env script as it is not longer relied on and only surfaces
false positives/known mismatches at this point.

Since our tooling now acts using vendored code where needed, this is no
longer as necessary as it previously was.

PR Close angular#39980
