1. tools: disable LTO for "v8_cppgc_shared" target …

   "PushAllRegistersAndIterateStack" is implemented in assembly and
   called from "stack.cc" via 'extern "C"'. [1]
   
   However, LTO does not work well with symbol usage from assembly. [2]
   
   This change workarounds the issue by disabling LTO for the target.
   
   With GCC 10 and "./configure --enable-lto", compilation succeeds
   after this change.
