trunks: Add ptr() method to ScopedKeyHandle
This method allows us to directly access the handle in the
ScopedKeyHandle object, so that we can use it in methods like LoadKey
Sample code looks like this:
ScopedKeyHandle key(factory);
LoadKey(key_blob, key.ptr(), ...);
Encrypt(key.value());
This makes code for trunks clients a little simpler, since the
ScopedKeyHandle can be declared before the Load operation as opposed
the old operation which declared a TPM_HANDLE* and then wrapped it in
a ScopedKeyHandle.
