It is probably fair to conclude that naming this dialect `StaticLogic` has been a pain point for a while. This commit proposes a dialect renaming to `Pipeline`, for a couple of reaons:
1. So far, we've only been working with pipeline abstractions within this dialect.
2. Pipeline representations aren't necessarily statically scheduled - we plan on adding switches to select between latency sensitive and latency insensitive lowerings of pipelines.
This name change does not preclude renamings in the future if we want to fit more stuff into this dialect. Personally, i think it is prudent to maintain a dialect name which reflects what's actually being done within the dialect, as well as the (near/mid/"someone actually intends to work on this"-term) future plans for the dialect.

This dialect is going to contain the CHIRRTL operations and types
currently in the FIRRTL dialect. This will provide better structuring
in the MLIR types as we don't want CHIRRTL types to be FIRRTL types.
For more information see this issue here:

Currently, the Moore frontend-compiler parses SystemVerilog, lowers the AST to Moore MIR, and then generates HW/Comb/LLHD code which it forwards to CIRCT.
This new Moore dialect aims to move the MIR into CIRCT to benefit from the CIRCT/MLIR infrastructure. In the long-run also the parser and AST can be implemented to have a complete SystemVerilog frontend natively in CIRCT.
The purpose of Moore MIR in the lowering chain is to make all the implicit things (e.g., type casts) in SystemVerilog explicit to ease further lowering to HW/Comb/LLHD.

Model of the compreg op outlined in the Seq dialect rationale dialect. This is just a starting place and I do expect it to change and/or have siblings for different flavors. Lowers to sv.alwaysff with posedge clock and sync reset -- for now.
Also adds a few mechanical things required to make the Seq dialect actually work which I neglected in the PR which added the dialect.
This is needed to fix a crash in DCE for graph regions. [0]
- alloc and store operations have been moved to a new MemRef dialect
- custom dialect types now need to be registered in the same compilation
unit as the type's storage. Any dialect that registers types have had
the logic moved to DialectTypes.cpp.
- Small change to the ResetTypeAttr default value declaration.

This change cargo-cult imports InitAllDialects.h and InitAllPasses.h
from MLIR.
`circt-opt` has been greatly simplified by using the more powerful
version of `MlirOptMain`, which supersedes all our current
command line options.
Now we're not preloading all dialects, we need to make sure that target
dialects are properly registered in all conversion passes. Source
dialects do not need to be manually loaded.
One thing which is not clear is if `circt::registerAllDialects` should
register any standard MLIR dialects which are used heavily throughout
CIRCT. This change only registers CIRCT dialects.
