This is the first PR in a longer chain that adds basic SV support to
CIRCT.
Add the Slang Verilog frontend as a CIRCT dependency. This will be the
foundation for CIRCT's Verilog parsing, elaboration, type checking, and
lowering to the core dialects. By default, Slang is built as a static
library from scratch, which is then linked into the new `ImportVerilog`
conversion. Alternatively, CIRCT can also be linked against a local
Slang installation provided by the system.
Add the `ImportVerilog` conversion library. This library statically
links in the Slang dependency and wraps it in an exception-safe,
LLVM-style API. Currently this only consists of the `getSlangVersion`
function and the necessary linking flags to get it to link statically
against Slang.
Add the `circt-verilog` tool, which will provide a fully-flegded
interface to the new `ImportVerilog` library. Later on we'll also add an
MLIR translation library for single-file SV import. But in general, SV
builds take a lot of command line options (macros, search paths, etc.)
and multiple input files, which is why we have a dedicated tool. All the
tool does at the moment is print the linked Slang version. More to come.
Note that this intentionally links against **version 3** of Slang. Newer
versions are available -- 4 and 5 as of this commit -- but they rely on
fairly new C++ compiler features that didn't work out of the box in our
CI images. We'll eventually want to upgrade, but for now Slang 3 is
sufficient to get the ball rolling.
See https://github.com/MikePopoloski/slang for details on Slang.

This adds a -shared-libs option to llhd-sim that is analogous to the
same option for mlir-cpu-runner. If specified, those libraries are
passed to the ExecutionEngine to dynamically load and link.
* Scaffolding for Capnp-dependent ESI code
* Adding 'capnp' feature
* Replicated functionality
* Just missing the complex part: schema parsing
* Parse the generated schema, get the size out of that
* Documentation
* Adding NOLINT
This also updates the README to include some building information.
Lots of caveats:
- This is all experimental
- The actual tool isn't interesting yet.
- The naming is arbitrary and will likely change.
- Much of the cmake files were cargo culted from other places
because I don't know what I'm doing.
