Attempts to pull drive ownership into DiskController.
...
For the sake of being more intelligent as to drive clocking, hopefully. And, eventually, to support multiple drive selection.

Ensures the Electron Plus 3 properly announces drives to an activity observer.
...
Does away with lazy allocation as not all that helpful, and liable to cause complexity.

Adjusts the 1770 not to talk directly to the drive about motor status.

Ensures all parts of the Electron have a fully-defined initial state.
...
Specifically to resolve an error with shift being pressed at startup due to a failure to establish a default value for that flag, but applying the same principle across the board.

Similar fix to that over in Oric land: ensure a known, effective initial value for the Plus 3's control register.

It would appear the 1770 and 1773 actually differ in relation to the (non-sensical) ability not to spin-up for a Type 2, and whether a side compare can occur. So the WD1770 class now requires a personality to be specified. Which it singly fails to honour.

Fixed potential bug whereby inserting a disk into a drive that hadn't been lazily allocated yet but had already been selected wouldn't take effect.

Made a first stab at enabling multi-disk machines and thereby obeying (some of) the Plus 3's status register.
