Bug 1766268 - Update eslint-plugin-mozilla's version of estraverse to fix issues with private identifiers. r=mossop

Due to babel still requiring an old version of estraverse, this disables our setup checking for changes
to modules in the eslint-plugin-mozilla package.json. For now, we'll need to remember to ensure there
is a top-level update to go with any changes - though that normally happens anyway.

For good measure, this also updates some of the top-level modules to ensure that node_modules is re-installed for everyone.

Bug 1622717: When parsing an AST allow the chosen parser to override the default scope manager and visitor keys. r=Standard8

There appears to be a bug in babel-eslint where it still uses the old
`ExperimentalSpreadProperty` and `ExperimentalRestProperty` node types when
babel itself (and hence the AST visitor keys) have switched to `SpreadElement`
and `RestElement`. I suspect there isn't much point in filing a babel-eslint
issue for this, they are currently in the process of working on v11 which does
fix the issue but is currently only available as a beta release.

There are three alternatives:

1. Use the beta babel-eslint.
2. Hack the visitor keys to include the old node types.
3. Traverse the AST changing the nodes from the old types to the new types.

Using a beta version is probably not a great idea so this patch does 2 which is
the simplest of the other options. It does have the drawback however that if
any eslint rules we use rely on the new node type names they will fail to work.

Bug 1617959: Switch to the babel-eslint parser and turn on support for optional chaining and nullish coalescing operator syntaxes. r=Standard8

The babel-eslint parser defaults to assuming all scripts are modules. Although
we're moving in that direction it seems reasonable to set the default as regular
scripts for now. All the places that were previously overriding the parser are
already specifying the sourceType in their eslint configs.

I chose to put the babel config in a file that babel itself won't look to avoid
the risk of this config impacting the use of babel elsewhere in the tree.
