feat(minifier): minify x ? 1 : 0 to +x or +!!x

[costajohnt]

Closes #20288

Adds numeric conditional expression optimization to the minifier:

• x ? 1 : 0 → +x when x is known boolean (saves 3 chars)
• x ? 1 : 0 → +!!x when x is unknown type and no parens needed (saves 1 char)
• x ? 0 : 1 → +!x when no parens needed (saves 2 chars)
• Skips when parentheses would make the result the same length or longer (e.g., a+b?1:0)

Profitability checks are based on the lessons from swc-project/swc#9920.

Implementation note: uses DetermineValueType to check if the test expression is boolean, and a simple test_needs_parens helper (matching BinaryExpression, LogicalExpression, etc.) to determine if wrapping would negate the savings.
