New Type "RequiredByValueExcept<T, ValueType>", "PartialByValueExcept<T, ValueType>"

[black7375]

Is your feature request related to a real problem or use-case?

This is useful when defining parameter values ​​for functions.

Describe a solution including usage in code example

interface optionI {
  inputPath: string;
  outputPath: string;
  format: string;
}

const defaultOption: RequiredByValueExcept<optionI, 'inputPath' | 'outputPath'> = {
  format: 'txt'
};

function foo(text: string, option: PartialByValueExcept<optionI, 'inputPath' | 'format'>) {
  // ...
}

Who does this impact? Who is this for?

I think this would be useful for defining default values ​​and parameters.
