This patch implements the access of private accessors by loading the
referenced component from the AccessorPair associated with private
name variables. It also makes the error messages for invalid kind
of private accessor access more specific.

This patch implements the declaration of private accessors.
When iterating over the class properties, we track private
accessors associated with the same name in a ZoneHashMap.
Once we get to all the necessary components for a private name
(we know statically whether we should expect only a setter,
only a getter, or both), we emit a call to a runtime function
`CreatePrivateAccessors` that creates an AccessorPair, and
store the components in it. The AccessorPair is then associated
with the private name variable and stored in the context
for later retrieval when the private accessors are accessed.

This patch adds:
- VariableMode::kPrivateMethod
- VariableMode::kPrivateSetterOnly
- VariableMode::kPrivateGetterOnly
- VariableMode::kPrivateGetterAndSetter
And replace the previous RequiresBrandCheckFlag by inferring
whether the brand check is required from these VariableModes.
It is then possible to check duplicate non-complementary
accessors in the parsers and throw early errors, and allow
complementary accessors to be associated with the same
private name variable.
This patch also adds the following AssignType:
- PRIVATE_METHOD
- PRIVATE_GETTER_ONLY
- PRIVATE_SETTER_ONLY
- PRIVATE_GETTER_AND_SETTER
corresponding to the new VariableModes so that it's possible
to generate specialized code for different type of
private accessor declarations.
