Change the type of 'uriComponent' (passed to 'encodeURIComponent') fr…

…om 'string' to 'string | number | boolean'. Fixes #18159 (#31103) - According to the ECMAScript 5.1 spec (§15.1.3.4), 'encodeURIComponent' invokes the abstract operation 'ToString': https://www.ecma-international.org/ecma-262/5.1/#sec-15.1.3.4 - In the spec (§9.8), 'ToString' accepts an 'Undefined', 'Null', 'Boolean', 'Number', 'String' or 'Object' argument: https://www.ecma-international.org/ecma-262/5.1/#sec-9.8 - TypeScript’s 'StringConstructor' accepts an argument with type 'any': https://github.com/Microsoft/TypeScript/blob/b0100100a18d740ad0b7c626bc81b800b5273ece/lib/lib.es5.d.ts#L518
