Does Pi do USB device "emulation" (has it "gadget" drivers)?

Not all of them, but the A, A+ and zero do. Basically all models _without_ a built-in USB hub work. The Pi 4 is capable of OTG only over the USB-C port, and only with a recent firmware.

They support a bunch of modes, like Mass Storage, Ethernet, Serial, HID, etc.
