Move CSP code into one entrypoint (#37604)

Browse source 
This refactoring moves various CSP-related methods away from GlobalScope
and Document into a dedicated entrypoint. It also reduces the amount of
imports of the CSP crate, so that types are consolidated into this one
entrypoint. That way, we control how CSP code interacts with the script
crate.

For reviewing purposes, I split up the refactoring into separate
distinct commits that all move 1 method(group) into the new file.

Testing: no change in behavior, only a build improvement + code cleanup
