flake8-builtins (A) rules that shouldn't apply to stubs

[Avasam]

The following I'm pretty sure should be disabled in stubs, as they are out of a stub author's control:

• builtin-variable-shadowing (A001) (344 hits in typeshed)
  This happens with aliases and other top-level variables. Non-runtime type aliases should be private in the first place. Devs also shouldn't try to import builtins from a module that happens to import said builtin. And finally this rule mostly tries to protect against using the shadowed variable. In a typing-only context, you should mostly be guarded by type tests anyway.
• builtin-argument-shadowing (A002) (2085 hits on typeshed)
• builtin-attribute-shadowing (A003)
• builtin-module-shadowing (A005) (done in [flake8-builtins] Disapply A005 to stub files #15350)

As for the rest:

• builtin-import-shadowing (A004) (53 hits in typeshed, nearly all re-exports)
  Very similar as A001 but can actually be worked around with import aliases and re-export aliases. (which would trigger A001 instead)
  Could maybe be ignored in stubs if re-exported ? (import print as print, from tensorflow.math import abs as abs, import foo as print; print = print and import foo as print; __all__= ["print"])
• builtin-lambda-argument-shadowing (A006)
  I don't think lambdas apply to type stubs anyway. Probably doesn't need to be ignored.

builtin-module-shadowing (A005)

This has been tackled in #15350
