web: Remove thread-loader from Webpack
Created by: plibither8
Should be merged before https://github.com/sourcegraph/sourcegraph/pull/39381.
The SentryWebpackPlugin does not work with thread-loader, since thread-loader doesn't have access to webpack options, thus it cannot access query params of the loader. See https://github.com/getsentry/sentry-webpack-plugin/issues/272#issuecomment-942381393.
Secondly, thread-loader itself has not shown any substantial performance or build-time improvements.

Test plan
Builds are passing with green checks without thread-loader.
