Optimize with thread loader and terser (#27014) (#27426)

* multi thread expensive loaders * revert styles * feat(NA): added thread-loader and cache-loader to base optimizer and dll compiler. * feat(NA): added cache-loader and thread-loader to the optimizer and dll compiler. * feat(NA): use new terser plugin instead of old unmaintained uglifyjs webpack plugin. * refact(NA): remove unused configs from base optimizer and dll compiler. * fix(NA): available cpu calculated number. * docs(NA): fix comment about what we are doing in prod on base_optimizer config. * docs(NA): explain why we are setting memory into each thread loader worker. * fix(NA): add dev only loaders to the thread-loader warmup config. * refact(NA): change name from babelCacheDir to babelLoaderCacheDir. * fix(NA): logic for calculating available cpus. * feat(NA): pass NODE_OPTIONS along for the optimizer forked process and also for the optimizer workers. * feat(NA): remove terser webpack plugin compression from base_optimizer and only run it on dll compiler. * chore(NA): update function to calculate available cpus for works. * fix(NA): apply upperbound to the number of workers we can have on thread-loader. * fix(NA): decrease the max number of thread pool workers. refact(NA): use the same calculated number of cpus to use on parallel tasks on thread loader pool config for terser parallel. refact(NA): lower down the poolTimeout on non dev mode. refact(NA): change devOnlyModules to nonDistributableOnlyModules on warmupThreadLoader config. * chore(NA): update yarn lock deps after merging with master.
