gatemate: Set unused BRAM inputs to 'bx
...
This will reduce the number of CPEs to generate fixed values at the block RAM inputs, if it is not used.

synth_gatemate: Add block RAM cascade support
...
* add simulation model for block RAM cascade in 40K mode
* limit 20K_SDP and 40K_SDP to 40 and 80 bits (the only useful configurations)

synth_gatemate: Revise block RAM read modes and initialization
...
* enable mixed read-width / write-width ports in SDP mode
* fix NO_CHANGE and WRITE_THROUGH behavior during read access
* remove redundant zero-initialization
* set A/B_WE bit during map (gatemate_bramopt pass could be removed later)
* differentiate "upper" and "lower" initialization for cascade mode
