Do not print "Failed to load asset at path: ...dart_sdk.js." message #49002
Description
We get a lot of legitimate bug reports where users assume the cause being the following error:
[ +304 ms] Failed to load asset at path: packages/build_web_compilers/src/dev_compiler/dart_sdk.js.
Status code: 404

However, that error is a red herring. We should not print this error so that users (and our own team) get to the root cause of their real issues quicker.
