string(TIMESTAMP): add %f specifier for microseconds
The %f specified extends the string(TIMESTAMP) and file(TIMESTAMP) commands to output the timestamp with a microsecond resolution. This convention is offered by python's datetime module. Before, the precision was limited to seconds. The implementation is done by extending existing cmTimestamp methods with a `microseconds` parameter. This parameter is optional in order to be backwards compatible. The timestamps are now received in a cross-platform manner using libuv, since the standard C functions like time() don't allow for sub-second precision. This requires libuv 1.28 or higher. We already require higher than that on Windows, so update the required version for other platforms. Implements: #19335
