Subject: Setting to disable DFU and FS access (#1891)

* Expose SystemTask dependency controllers

Expose NotificationManager and Settings for use by the feature in next commit.

This is a memory efficient way for accessing SystemTask dependencies from
controllers that have SystemTask injected as a dependency.
Looks like each direct dependency injection uses 4 bytes RAM.
As InfiniTime is close to running out of RAM (using 16 more bytes causes build
to fail with "ld: region RAM overflowed with stack") it might be helpful to use
this approach more.

* Add setting to disable DFU and FS access
