Fix automatic CSP hash update

Browse Source 
The problem was that whenever the hashe needed an update, the current
patch would create a conflict which cannot be easily auto-resolved.

Instead, put the hashes in a separate patch that is deleted and
regenerated each time, avoiding the conflicts.

Also the web worker iframe hash was not being updated.

Normally webviews are served from vscode-webview.net but we would rather them be
self-hosted.
When doing this CSP will block resources (for example when viewing images) so
add 'self' to the CSP to fix that.
Additionally the service worker defaults to handling *all* requests made to the
current host but when self-hosting the webview this will end up including the
webview HTML itself which means these requests will fail since the communication

To test, open a few types of webviews (images, markdown, extension details, etc).
Make sure to update the hash. To do so:
1. run code-server
2. open any webview (i.e. preview Markdown)
3. see error in console and copy hash
That will test the hash change in pre/index.html
Double-check the console to make sure there are no console errors for the webWorkerExtensionHostIframe
which also requires a hash change.

This fixes webviews from not working properly due to a change upstream.
