perf: don't request unnecessary output

[DaniPopes]

We're currently requesting all evm.bytecode (and evm.deployedBytecode) output by default. This includes evm.bytecode.generatedSources, introduced in solc 0.8.0, which is a list of potentially huge Yul AST objects that is completely unused in Foundry.

Only request the Compact* bytecode fields in the defaults.

This cuts down a clean forge build:

• from 2:20m to 1:30m (-36%) on superform-xyz/superform-core
• from 1:39m to 1:29m (-10%) on sablier-labs/v2-core
• from 54.5s to 45.7s (-20%) on sablier-labs/v2-core (FOUNDRY_PROFILE=lite which is optimizer = false)

It may have a larger impact when compiling with >=0.8.28, because the cache storing this data was removed in that version (ethereum/solidity@3c5e46b), or when optimizations are disabled as more IR will be generated and output to JSON.

I verified that these inputs are accepted by solidity 0.4.14, 0.6.3, 0.8.28, and vyper 0.3.10, 0.4.0. All of these outputs are supported by all of them except for vyper which needs to be normalized.

Drive-by: buffer stdin when writing to the solc subprocess.
