Add option to skip overriding assets: tasks

[mipearson]

Hi,

I'm looking at moving our application off of my gem webpack-rails and on to webpacker and also writing a guide for others to do so, with the intention of sunsetting webpack-rails.

Our application builds the sprockets assets and webpack assets separately. By doing so, we can do some clever caching to avoid having to build our webpack assets (which takes ~40s in CI) on every CI build. I'd like to preserve this behaviour.

I'd like to submit a pull request to add an option to config/webpacker.yml that disables the Rake::Task[*].enhance calls in webpacker.

Would this be acceptable?

Really janky, hopefully temporary workaround:

%w{assets:clobber assets:precompile}.each do |task_name|
  Rake::Task[task_name].instance_eval do
    @actions.reject! { |action| action.source_location[0] =~ /webpacker/ }
  end
end

I think you should write that PR. Thanks for taking time to look at this.
