Reduce build size

[afrokick]

From issue: #10902

In the issue @SimonSimCity mentioned:

When running meteor build --server-only on a clean project (just freshly created by the command meteor create test-project) I end up with a folder of a size of 118mb - of which 74mb is taken up by programs/server/npm/node_modules/meteor/babel-compiler. I'm quite unsure if the rest wouldn't be needed, but if we could get out the babel-compiler here, that would decrease the size of our final bundle considerably.

@ensemblebd had a workaround

Another interesting issue #10230

What we can do

Remove dev dependencies from build

Packages like TypeScript, PostCSS and etc. can be safely remove because it is "build step" tools.

Remove duplications from build

There are multiple versions of the same package in different places. That's how Meteor packages system work. But maybe we can build one package graph for all deps and use it in meteor packages.

The benefits

• Smaller image(archive) size => decreasing bandwidth usage when deploying app.
• Faster build time (we can install all deps tree at once without duplications in sub folders). ???
