d4c9db7fcf Move disk image reading to be behind an ImgFile class 
Allows different implementations for different platforms (the JS
build relies on browser APIs to stream disk images over the network).

Setting aside the JS build, this also reduces some code duplication.

35c86ad6bf Clean up #includes 
Result of running IWYU (https://include-what-you-use.org/) and
applying most of the suggestions about unncessary includes and
forward declarations.

Was motivated by observing that <thread> was being included in
ppcopcodes.cpp even though it was unused (found while researching
the use of threads), but seems generally good to help with build
times and correctness.

ea0eae467d Add assertion for valid SCSI IDs when updating control lines 
Would have flagged the out-of-bounds write fixed by
dingusdev/dingusppc@36cb84eaaa sooner.

0bd9d0e973 Fix HWComponent name initialization. 
First, remove name override for subclasses of HWComponent (Chaos and ScsiBus) because HWComponent has its own name field.

HWComponent name should be set as early as possible in the constructor so it can be used in log messages.
PCIDevice should set name of HWComponent (through MMIODevice) in its constructor, using the name that is given to its constructor.
For Bandit and Grackle, they don't need to set the HWComponent name since its PCIDevice constructor will now do it.
Chaos is not a PCIDevice so it should set the MMIODevice name itself.
Why does PCIDevice have a name that is separate from the HWComponent name?
