benchmark: use typescript for import cjs benchmark

The original benchmark uses a not very realistic fixture (it has
a huge try-catch block that would throw on the first line and then
export at the end, hardly representative of real-world code).
Also, it measures the entire import including evaluation, not just
parsing. This updates the name to import-cjs to be more accurate,
and use the typescript.js as the fixture which has been reported
to be slow to import, leading users to use require() to work around
the peformance impact.
