If a page has a Content Security Policy header and the `script-src` (or
`default-src`) directive does not contain neither `wasm-unsafe-eval` nor
`unsafe-eval` loading and executing WebAssembly is blocked in the page
(although it is still possible to load and execute WebAssembly in a
worker thread).
Although the Nextcloud classes to manage the CSP already supported
allowing `unsafe-eval` this affects not only WebAssembly, but also the
`eval` operation in JavaScript.
To make possible to allow WebAssembly execution without allowing
JavaScript `eval` this commit adds support for allowing
`wasm-unsafe-eval`.

Reuse Request::USER_AGENT_FIREFOX, and also update the safari detection
since safari < 12 is not supported anymore and we can remove a bit of
code duplication

To continue this formatting madness, here's a tiny patch that adds
unified formatting for control structures like if and loops as well as
classes, their methods and anonymous functions. This basically forces
the constructs to start on the same line. This is not exactly what PSR2
wants, but I think we can have a few exceptions with "our" style. The
starting of braces on the same line is pracrically standard for our
code.
This also removes and empty lines from method/function bodies at the
beginning and end.

This introduces and event that can be listend to when we actually use
the CSP. This means that apps no longer have to always inject their CSP
but only do so when it is required. Yay for being lazy.

Fixes#11035
Since the child-src directive is deprecated (we should kill it at some
point) we need to have the proper worker-src available

With 10.0.1 CSPv3 is broken in Safari if it doesn't run from a local IP. Awesome.
=> Let's remove this for Safari and keep chrome and Firefox in the whitelist.
