Catherine 5d9ad62f36 build.plat,vendor: start build.sh with #!/bin/sh. 
The build scripts generated by Amaranth are designed to be invoked by
directly running them with any shell (some of them will re-invoke
themselves with `bash` specifically, when it's a toolchain requirement),
and they're not currently marked executable, so there's no shebang.

Add a shebang line to improve compatibility with cases where they are
treated as executables in their own right.

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.

Catherine 7d99981d57 Implement RFC 15: Lifting shape-castable objects. 
See amaranth-lang/rfcs#15 and #784.

Note that this RFC breaks the existing syntax for initializing a view
with a new signal. Instances of `View(layout)` *must* be changed to
`Signal(layout)`.
