feat: added common strategies applicable to all properties

[soumyamahunt]

Added support for applying common strategies (like ValueCoder) to all properties of a type using the @codable macro's commonStrategies parameter.

Features:

• Added HelperCoderStrategy for specifying common type conversion strategies
• Added CodableCommonStrategy for use with @codable macro
• Added StrategyFinder to extract and apply common strategies during macro expansion
• Added comprehensive test suite for common strategies functionality

Example usage:

@Codable(commonStrategies: [.codedBy(.valueCoder())])
struct Model {
    let int: Int      // Uses ValueCoder<Int>
    let url: URL      // Uses standard Codable (not ValueCodingStrategy)
    let string: String // Uses ValueCoder<String>
}

resolves #93, resolves #51
