script: Wrap unsafe code in components/script/bindings in unsafe {} (#38544)

Browse source 
Clippy now checks to see if unsafe code is wrapped in unsafe blocks. We
have this lint disabled for `script` and `script_bindings` because of a
lot of legacy code that doesn't do this. The lint is useful though as it
makes it more obvious what code is unsafe. This is an incremental step
toward being able to turn this lint on for `script`.

This has the benefit of silencing warnings that show up in some IDEs
that use rust-analyzer.

Testing: This should not change behavior at all and is thus covered by
existing tests.
