Marcelina Kościelnicka 8c4a15ab92 hdl.mem: lower Memory directly to $mem_v2 RTLIL cell. 
The design decision of using split memory ports in the internal
representation (copied from Yosys) was misguided and caused no end
of misery. Remove any uses of `$memrd`/`$memwr` and lower memories
directly to a combined memory cell, currently the RTLIL one.

Catherine a921261215 build.run: add env= argument to BuildPlan.execute_local(). 
Build scripts are explicitly intended to have overrides that are
done through the use of environment variables, and right now this
would require a very awkward `run_script=False` invocation followed
by copying a bit of code out of the Amaranth codebase, which is
clearly suboptimal.
