perf(compiler-sfc): remove magic-string trim on script

magic-string's trim method uses a regex check for aborting which turns
out to be extremely expensive - it cna take up to 10% time in total SFC
compilation! The usage here is purely aesthetic so simply removing it
for a big perf gain is well worth it.
