Improve forge script --json output and handling of --silent

[zerosnacks]

Component

Forge

Describe the feature you would like

Currently when passing the --json flag the following is returned:

foundry/crates/script/src/lib.rs

Lines 496 to 501 in f0d9eec

	#[derive(Serialize, Deserialize)]
	struct JsonResult {
	logs: Vec<String>,
	gas_used: u64,
	returns: HashMap<String, NestedValue>,
	}

It would be beneficial to return more information, as defined by ScriptResult

foundry/crates/script/src/lib.rs

Lines 462 to 474 in f0d9eec

	#[derive(Default)]
	pub struct ScriptResult {
	pub success: bool,
	pub logs: Vec<Log>,
	pub traces: Traces,
	pub debug: Option<Vec<DebugArena>>,
	pub gas_used: u64,
	pub labeled_addresses: HashMap<Address, String>,
	pub transactions: Option<BroadcastableTransactions>,
	pub returned: Bytes,
	pub address: Option<Address>,
	pub breakpoints: Breakpoints,
	}

In turn it would also be useful to define a JSON schema for the output (#7813)

I've also noticed that alongside the JSON a lot of other lines are written to stdout making it difficult to cleanly capture the output. If --silent is passed and the --json flag is enabled only the JSON should be returned. It appears --silent is currently only applied to the compilation output during the build phase.
