JSON Representation of CompilerOutput Incorrect

Platform
Linux 5.10.114-1-MANJARO x86_64 GNU/Linux

Description
The CompilerOutput JSON that is included in the BuildInfo is causing Hardhat to crash because it is serializing the bytecode and deployedBytecode with a 0x prefix while solc does not prefix those hex strings with 0x prefixes. This difference causes the conversion from a string to buffer in hardhat to fail and subsequently crash.

If the build info files generated by foundry are present, it will crash hardhat due to this reason.

this is so annoying lol

we explicitly added 0x prefixes for artifacts which use the same types as CompilerOutput, I'm not sure yet what would be the simplest solution here

The 0x prefix is so standard at this point, if solc updates then it'll break a ton of tooling so idk we might be stuck with things like this
