Introduce `abstract_mem_t` to allow custom implementations

Add Smcsrind/Sscsrind support
This adds the following CSRs:
miselect (0x350), mireg (0x351), mireg2/3 (0x352, 0x353),
mireg4-6 (0x355 - 0x357), siselect (0x150), sireg (0x151),
sireg2/3 (0x152, 0x153), sireg4-6 (0x155 - 0x157), vsiselect (0x250),
vsireg (0x251), mireg2/3 (0x252, 0x253), vsireg4-6 (0x255 - 0x257).
Presently, attempts to read / write from ireg? registers will fail, and
future extensions will provide proxy CSR mappings for the respective
?ireg CSRs.

mcontrol/mcontrol6 triggers on cbo.flush/clean
The mcontrol/mcontrol6 store address before has a higher priority over page
faults and access faults. Thus, trigger checking should before the translate().
This commit checks all address of the cache block.

Let debugger control hart availability
This change lets me test OpenOCD's behavior when harts become available.
It only affects how things look to the debugger. Harts that are
"unavailable" still execute code as usual.
Control is implemented through the 2 LSBs of the DMCUSTOM register in
the Debug Module.
