Parse --cpu-set as ParseIntList

An argument of --cpu-set=1,2,3 is currently parsed into a
vector<int32_t>. This causes two problems:

1. With the type CmdlineType<std::vector<int32_t>> that internally does
   the comma spliting, it prevents us from adding another type of int
   vector (e.g. multiple --dex-fd $FD). This is inconsistent to existing
   string and vector<string> parsing.

2. A delimiter-separated argument like "-Xbootclasspath:" is parsed with
   ParseStringList, which keeps the types of "string vector" seperated
   (depending on whether it comes from a single argument, like
   "-Xbootclasspath:", or multiple arguments, like --dex-file).

This change replaces the parser of vector<int32_t> with the new
ParseIntList, which solves the two problems above.
