Define host permissions and allowed protocols in webpack config

[raducristianpopa]

Just for testing purposes at the moment, since I was testing this on a local website.

Thoughts on moving the host permissions here

web-monetization-extension/src/shared/defines.ts

Lines 1 to 5 in 992b346

	import type { LogLevelDesc } from 'loglevel'
	declare const CONFIG_LOG_LEVEL: LogLevelDesc
	export const LOG_LEVEL = CONFIG_LOG_LEVEL

and define them in the webpack config based on the environment ala:

web-monetization-extension/webpack/dev.ts

Lines 42 to 44 in 992b346

	new DefinePlugin({
	CONFIG_LOG_LEVEL: JSON.stringify('DEBUG')
	})
