Reduce sharedmem addr mapping to 8KB

smem size is set to 16KB, and reqs exceeding this range gets filtered
out of smemNodes from inside the core. Lower 8KB is mapped to smem
banks, and upper 8KB is reserved for MMIO.

Don't set XLen in WithRadianceCores
...
Currently Vortex core uses hardcoded 32-bit xlen in its RTL. Also, setting this
here breaks instantiating Gemmini, which assumes 64bit. So just leave it
unchanged and try to treat Vortex as a special-case.

Split IO for lookup and dealloc in InflightTable
...
The usage of `lookup` and `lookupSourceId` ports were being conflated in
terms of table lookup and dealloc. Now `lookupSourceId` solely controls
lookup operation and vice versa. This simplifies pipeline reg logic in
uncoalescer.

Fix uncoalesced response being dropped

Need to use fire instead of valid so that the uncoalescing /

way to the response queues.

Streamline upstream flow with regards to CoalSourceGen
...
CoalescerSourceGen was prematurely reclaiming sourceIds in the presence
of coalResp backpressure, since it was not referring to coalResp.fire
and instead setting ready to always-true. With this change
CoalSourceGen properly propagates both downstream and upstream
backpressure.
