Update webpack output names

Context: in webpack v5, the files associated with the "core-vendors"
custom group are classified as initial (entry-point) chunk files [1]
when that was not the case in webpack v4. Not sure why.

Add [name] to filename to be more consistent with chunkFilename, and so
it's easier to understand the association between files and cacheGroups.

Update the bundlesize config glob patterns to match these new names.
Since the exact reason for filename vs. chunkFilename isn't clear to me,
I updated all glob patterns to match either.
