At #11342, getattr on parents and elements became faster, among other
tricks, by supplying a "lazy" error message
`sage.structure.misc.AttributeErrorMessage`. Namely, creating the error
message as a string, even as a ''lazy'' string, took too much time.
Here, I suggest to go one step further: `sage.structure.misc`,
`sage.structure.element` and `sage.structure.parent` should store a fixed
instance of `AttributeError` whose error message is a fixed instance of
`AttributeErrorMessage`. When raising an attribute error, one can then
just change the previously created error message in-place and then raise
the previously created `AttributeError`.
Hence, the time for ''creating'' the attribute error is saved.
