* Parse a new property value for a given property type.

* While the prop value can reasonably be expected to be of `any` type as far as TypeScript's type checker is concerned,
* it is not safe to assume that the string returned by evaluating `typeof propValue` matches:
* 1. `any`, the type given to `propValue` in the function signature
* 2. the type stored from `propType`.
*
* This function provides the capability to parse/coerce a property's value to potentially any other JavaScript type.
*
* Property values represented in TSX preserve their type information. In the example below, the number 0 is passed to
* a component. This `propValue` will preserve its type information (`typeof propValue === 'number'`). Note that is
* based on the type of the value being passed in, not the type declared of the class member decorated with `@Prop`.
* ```tsx
* <my-cmp prop-val={0}></my-cmp>
* ```
*
* HTML prop values on the other hand, will always a string
*
* @param propValue the new value to coerce to some type
* @param propType the type of the prop, expressed as a binary number
* @returns the parsed/coerced value
