Subject: chore: disallow copying CppHeapCreateParams

Experimental commit to resolve FTBS https://ci.appveyor.com/project/electron-bot/electron-ljo26/builds/36405680#L25345
which introduces a new struct CppHeapCreateParams that aggregates a
vector of unique_ptrs. Our Windows CI is unhappy that this struct
implicitly deletes its copy ctor, so this commit makes it explicit.
