cmd/abigen: support for reading solc output from stdin (#16683)
Allow the --abi flag to be given - to indicate that it should read the ABI information from standard input. It expects to read the solc output with the --combined-json flag providing bin, abi, userdoc, devdoc, and metadata, and works very similarly to the internal invocation of solc, except it allows external invocation of solc. This facilitates integration with more complex solc invocations, such as invocations that require path remapping or --allow-paths tweaks. Simple usage example: solc --combined-json bin,abi,userdoc,devdoc,metadata *.sol | abigen --abi -
