// returns the DEBUG_S_FUNC_MDTOKEN_MAP subsection as a byte array
// DEBUG_S_FUNC_MDTOKEN_MAP subsection contains method RVA to mdToken mapping
//
// contents of subsection:
// offset 0, 4 bytes: count of entries in the map
// offset 4, 8*N bytes: 4 byte RVA + 4 byte 'offset' relative to the start of 'method data'
// offset 4+8*N, * bytes: all method data packed sequentially with no padding. method data consists of
// 1 byte 'count' of generic parameters, 3 bytes of method's rid and 'count'
// variable sized ECMA formatted TypeSpec signatures for each generic parameter
//
// Compiler places the CTLToken (for a method) or the lexical funclet order (if a method has 1 or more funclets),
// which binder uses to compute the RVA.
//
// all entries are sorted by 'offset' field.
//
// 'offset' optimization: if the method has no generic parameters, we don't need to pass in a signature
// and can encode the mdToken of method in 'offset'
// We do this by setting the high bit of 'offset' and then storing rid part of
// token in last 3 bytes of 'offset'
