FEATURE: Remove 1K Dependencies & and separat webpack adapter extensibility package

[mhsdesign]

i started cleaning up more than initially thought with #3366 so this pr is made ontop on it ;)

solves: #3215

What i did:

• make @neos-project/neos-ui-extensibility a code only repo (eg no webpack, only the extensibilityMap.json and the shim js files)
• fix the shims code es transpilation (they are now also build by typescript into the dist folder)
• combine the webpack buildscript from @neos-project/neos-ui-extensibility and @neos-project/build-essentials into @neos-project/neos-ui-extensibility-webpack-adapter
• remove @neos-project/babel-preset-neos-ui (was forgotten)
• introduce new private @neos-project/neos-ui-build for all the esbuild specific plugins and other build scripts (this package will not be released)
• use an easy official plugin point to still have the package @neos-project/neos-ui-extensibility-webpack-legacy installed in the workspace but not its dependencies (we dont need webpack and babel anymore)
• remove storybook as dependency (looots of dependencies)
• remove 8year old git hook and init script no one uses :P (plus dependencies)
• remove outdated things from the Build/ folder in general
• remove ./docker-compose.yaml which is completely outdated and unused (uses node14 + webpack for building the ui, but we rather use node natively)
• remove unused clean command from each package gpristine is your friend ;)
• removed crossenv as we dont use NODE_ENV anymore to control the build
• extensibilty alias map as json: packages/neos-ui-extensibility/extensibilityMap.json

Todos:

• remove whole .story-book folder (separate pr for removing all stories)
• yarn dedupe '@babel/*'
• yarn dedupe prop-types

Ready to review.

Left over todos and discussions about the naming of the package @neos-project/neos-ui-extensibility-webpack-legacy will be handled in another pr - as otherwise things will get out of hand :D

Todos for next time:

• Design new esbuild extensibility api
  • do we want an actual esbuild plugin or just let people use esbuilds 0.16.10 alias feature: https://esbuild.github.io/api/#alias

require("esbuild").build({
    logLevel: "info",
    bundle: true,
    target: "es2020",
    entryPoints: {"Plugin": "src/index.js"},
    loader: {
        ".js": "tsx",
    },
    alias: require("@neos-project/neos-ui-extensibility/extensibilityMap.json"),
    outdir: "../../Public/NeosUserInterface",
})

• find a proper futureproof name for @neos-project/neos-ui-extensibility-webpack-legacy or use it
• move plugins and some helpers to @neos-project/neos-ui-build (when FEATURE: CSS build refactor (make react-ui-components easy to use) #3366 is merged to avoid merge conflicts)
• only publish dist to npm

i discussed the naming of @neos-project/neos-ui-extensibility-webpack-legacy with @fcool and we came to the conclusion to name it: @neos-project/neos-ui-extensibility-webpack-adapter

I just released a 8.3.0-beta1 8.3.0-beta2 8.3.0-beta3 for all the npm packages, so we can test this properly ;)

It looks good to me and I like the @neos-project/neos-ui-extensibility-webpack-adapter more than the legacy ... so thanks to @fcool :)

Again a remarkable but not so handsome PR ;)
