Is your feature request related to a problem? Please describe.
Currently, webpack sets process to undefined

 new webpack.DefinePlugin({
 "global.TNS_WEBPACK": "true",
 "process": undefined,
 }),

which breaks plugins like nativescript-nodeify that use browser versions of library in NS.

Describe the solution you'd like
Remove "process": undefined, or explain the reasoning behind it.

Describe alternatives you've considered
Manually disabling it, but I don't know what are the reasons it was set like that in the first place.

In my tests, commenting the line had no side effects besides making everything that was broken work.

Additional context
I'm developing a remote abstraction for @ngrx/store-devtools. This means using browser libs that do checks on process.browser and libs that use require('ws'). I managed to replace require('ws') with nativescript-websockets, but there isn't a way to use process without changing the default webpack behavior, and the reason for it doesn't seem to be listed anywhere besides "process is node specific" (NativeScript/NativeScript#3080 (comment))
