gdb: gdbarch.py: spell out parameters of _Component.__init__

The way _Component uses kwargs is handy to save a few characters, but it
doesn't play well with static analysis.  When editing gdbarch.py, my
editor (which uses pylance under the hood) knows nothing about the
properties of components.  So it's full of squiggly lines, and typing
analysis (which I find really helpful) doesn't work.  I therefore think
it would be better to spell out the parameters.
