In https://github.com/llvm/llvm-project/pull/182956 we stopped using the access specifiers and unconditionally set all access to `AS_public`. This patch is a follow-up cleanup to remove all the `AccessType` parameters of the `TypeSystemClang` APIs (which since https://github.com/llvm/llvm-project/pull/182956 are never used)
