Consolidate redundant dependencies in built binary

[flotwig]

Current behavior:

During prod builds, yarn is run in each subpackage individually:

cypress/scripts/binary/util/packages.js

Lines 180 to 199 in ffa8c9e

	const retryNpmInstall = function (pkg) {
	console.log('installing %s', pkg)
	console.log('NODE_ENV is %s', process.env.NODE_ENV)
	// force installing only PRODUCTION dependencies
	// https://docs.npmjs.com/cli/install
	const npmInstall = _.partial(yarn, ['install', '--production'])
	return npmInstall(pkg, { NODE_ENV: 'production' })
	.catch({ code: 'EMFILE' }, () => {
	return Promise
	.delay(1000)
	.then(() => {
	return retryNpmInstall(pkg)
	})
	}).catch((err) => {
	console.log(err, err.code)
	throw err
	})
	}

Desired behavior:

Run yarn in the root to take advantage of dependency hoisting. This will help reduce the overall binary size

This will require some reworking of the existing build process. Only production dependencies should be installed in the final .zip, but some dev dependencies are needed for the build process.
