Docs: static opt macro list
Also adds `docs/tests/macro_commands.py` which checks all commands in
`code_examples/macro_commands` against the current yosys build. Format similar
to `run-test.sh` files: logging the file under test and reporting errors.

Catherine fc5ff7a265 cxxrtl: always lazily format print messages.
This is mostly useful for collecting coverage for the future `$check`
cell, where, depending on the flavor, formatting a message may not be
wanted even for a failed assertion.

Catherine b74d33d1b8 fmt: rename TIME to VLOG_TIME.
The behavior of these format specifiers is highly specific to Verilog
(`$time` and `$realtime` are only defined relative to `$timescale`)
and may not fit other languages well, if at all. If they choose to use
it, it is now clear what they are opting into.

This commit also simplifies the CXXRTL code generation for these format
specifiers.

YRabbit ae991abf2e gowin: fix the BRAM mapping.
The primitives used have been corrected and changes have been made to the set of signals.
The empirically established need to set the OCEx signal to 1 when using READ_MODE=0 is reflected.

Catherine 905f07c03f cxxrtl: introduce `performer`, a context object for `eval()`. (breaking change)
At the moment the only thing it allows is redirecting `$print` cell
output in a context-dependent manner. In the future, it will allow
customizing handling of `$check` cells (where the default is to abort),
of out-of-range memory accesses, and other runtime conditions with
effects.

This context object also allows a suitably written testbench to add
Verilog-compliant `$time`/`$realtime` handling, albeit it involves
the ceremony of defining a `performer` subclass. Most people will
want something like this to customize `$time`:

    int64_t time = 0;
    struct : public performer {
      int64_t *time_ptr;
      int64_t time() const override { return *time_ptr; }
    } performer = { &time };

    p_top.step(&performer);

Catherine 02e3d508fa cxxrtl: remove `module::steps`. (breaking change)
This approach to tracking simulation time was a mistake that I did not
catch in review. It has several issues:
1. There is absolutely no requirement to call `step()`, as it is
   a convenience function. In particular, `steps` will not be
   incremented in submodules if `-noflatten` is used.
2. The semantics of `steps` does not match that of the Verilog `$time`
   construct.
3. There is no way to make the semantics of `%t` match that of Verilog.
4. The `module` interface is intentionally very barebones. It is little
   more than a container for three method pointers, `reset`, `eval`,
   and `commit`. Adding ancillary data to it goes against this.

If similar functionality is introduced again it should probably be
a variable that is global per toplevel design using some object that is
unique for an entire hierarchy of modules, and ideally exposed via
the C API. For now, it is being removed (in this commit) and (in next
commit) the capability is being reintroduced through a context object
that can be specified for `eval()`.

Catherine a33acb7cd9 cxxrtl: refactor the formatter and use a closure.
This commit achieves three roughly equally important goals:
1. To bring the rendering code in kernel/fmt.cc and in cxxrtl.h as close
   together as possible, with an ideal of only having the bigint library
   as the difference between the render functions.
2. To make the treatment of `$time` and `$realtime` in CXXRTL closer to
   the Verilog semantics, at least in the formatting code.
3. To change the code generator so that all of the `$print`-to-`string`
   conversion code is contained inside of a closure.

There are two reasons to aim for goal (3):
a. Because output redirection through definition of a global ostream
   object is neither convenient nor useful for environments where
   the output is consumed by other code rather than being printed on
   a terminal.
b. Because it may be desirable to, in some cases, ignore the `$print`
   cells that are present in the netlist based on a runtime decision.
   This is doubly true for an upcoming `$check` cell implementing
   assertions, since failing a `$check` would by default cause a crash.

Catherine bf1a99da09 cxxrtl: make observer methods non-virtual. (breaking change)
This avoids having to devirtualize them later to get performance back,
and simplifies the code a bit.

The change is prompted by the desire to add a similar observer object
to `eval()`, and a repeated consideration of whether the dispatch on
these should be virtual in first place.

Catherine ed81cc5f81 cxxrtl: rename observer::{on_commit→on_update}. (breaking change)
The name `on_commit` was terrible since it would not be called, as one
may conclude from the name, on each `commit()`, but only whenever that
method actually updates a value.
