Turbopack: CLI / perf improvements

[timneutkens]

What?

Some improvements to closer match other bundlers in the CLI.

• CLI: Add --no-sourcemap to cli
• CLI: Update browserslist query to match dev
• CLI: Add forget(turbotasks) to drop memory at end of build
• CLI: Remove styled-jsx, emotion, styled-components transforms by default
• Tracing: Add more spans for analyse modules step
• Analysis: Move some work intended to only run with an input sourcemap into the if options.extract_source_map
• Minify: Change to 2 passes, matching rspack default
