[clang] [NFC][analyzer] Get rid of imaginary friends (of classes) (PR #180188)

[Donát Nagy via cfe-commits]

https://github.com/NagyDonat created https://github.com/llvm/llvm-project/pull/180188

These NodeBuilder classes were deleted from the codebase in 2011 (fifteen years ago!) by 3eae33412d18c4a4a4a8592898b3e65ad5946a89 so don't declare them as friends.
