[TASK] Deprecate `top.rawurlencode` and `top.str_replace`

The global JavaScript functions `top.rawurlencode()` and
`top.str_replace()` were introduced in 2009 and have been marked as
deprecated now. The code is not required and some special handling used
in these functions may get achieved with native JavaScript functions.
