Force URAM Usage for ML and SMC Memories

BRAM utilization was approximately 90% prior to change. This appeared to
be the cause of build failures.

This change effectively change targets large u_ram1p_ram_smc and
u_ml_dmem RAMs and requests the vivado tool to set these to URAM with
new synth only constraint (synth.xdc).

Louhi build available temporarily here
https://louhi.dev/5958780716318720/execution-detail/4590981286068224

Build is successful and imp utilization report available in the logs at
the above Louhi link shows the following utilization changes:
URAM utilization increase to ~31% (from ~1%)
BRAM utilization reduced to ~13% (from ~90%)
