Implement the type of Flip<T>. Flip transforms an object type by swapping its keys and values. The keys in the resulting object will be the values from the input, and the values will be the keys from the input.

For example:

Flip<{ a: "x", b: "y", c: "z" }>; 
// {x: 'a', y: 'b', z: 'c'}

Flip<{ a: 1, b: 2, c: 3 }>; 
// {1: 'a', 2: 'b', 3: 'c'}

Flip<{ a: false, b: true }>; 
// {false: 'a', true: 'b'}

No need to support nested objects and values which cannot be object keys such as arrays
