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.
