fix(compiler): don't use project-wide config

[midzelis]

Details

Modify the lwc compiler to avoid using the project wide babel.config.js file. This was discovered when adding support to LWC LSP when opening standalone projects. If that standalone project was using a babel.config.js file, it was interfering with the lwc compiler babel transforms, which should be isolated. lwc compiler already pases babelrc: false as a default option. babelConfig: false is the way to disable the project wide config. Project wide configs are new in babel 7.x.

Move this flag to the BABEL_CONFIG_BASE from (the import is ../babel-plugins)

[pmdartus]

Except for @diervo comment, it looks good to merge.
