remove polyfill packages to support webpack 5

[luu-alex]

connected to #5031 in order to support create-react-app and angular5 out of the box with web3js we need to get rid of these dependancies from our library:
crypto-browserify,
stream-browserify,
assert,
stream-http,
https-browserify,
os-browserify,
url

+1 on this. This causes a lot of problems for bundling and tons of workarounds need to be injected to get things working.
