Remove ngfactory deps

we have several of these deps which shouldn't be needed - the angular compiler should get any references from transitive deps using the ngsummary files.

Maybe just switching to Ivy is another approach here - but ideally Bazel users who can't adopt Ivy still shouldn't need to add these deps to make the compile succeed.

As far as I know, ivy will work with ts_library directly. I saw your work on the main angular repo which contains a ts_plugin for ngtsc.
I'm just curious when we'll get rid of @angular/bazel package because building an angular app is so hard currently.

[alexeagle]

yeah compiling angular with the ts_library rule should make this a lot easier. @alxhub will probably do a refactoring in ngtsc soon which unblocks that work.

What's the current ETA? May I know that?. Thank you for the information.

[alexeagle]

I don't have an ETA - @alxhub has been busy making Ivy work. Maybe we can find someone else to pick it up.
In the meantime this repo is moving to rules_nodejs, and we'll be on Ivy soon which I think will make this problem go away?

Moving to bazel-contrib/rules_nodejs#1128 so we don't lose it when I archive this repo
