Purge legacy HTIF things

The SCR file is gone, too, because it was tightly coupled. The

Avoid need for FENCE.I in debug programs
...
This is a hack to work around caching the (uncacheable) debug RAM. The
RAM is always entered with a JALR, so flush the I$ on any debug-mode JALR.

Always verify BTB result; don't bother flushing it
...
This improves CPI for things like
lbu t0, (t0)
j foo
addi t0, t0, 1
where the addi would stall, causing j's misprediction check to fail,
flushing the pipeline.

Dynamically compute number of L1 client channels
...
Until now, the number of L1 client channels was set statically in the
configuration. This static configuration also assumed the same number of
cached and uncached channels per tile. As we plan to move towards
heterogenous multicore systems, this restriction should be removed.
This commit changes the generator so that number of channels per tile
can be independently set (using cde.Parameters.alterPartial).
The OuterMemorySystem will dynamically compute the number of cached and
uncached channels by summing the number of each kind of channel per core.

Refactor the TransactionTracker logic in all the L2 TileLink Managers.
...
They now share common sub-transactions within traits, and use a common
set of state transitions and scoreboarding logic. Tracker allocation
logic has also been updated. No changes to external IOs or the TileLink protocol.
A new bufferless Broadcast hub is also included, but does not yet pass fuzzing checks.
