Problem: ml_get error when changing hidden buffer in Python.
Solution: Block updating folds. (closesvim/vim#7598)
----
"ctx_switch()", "ctx_restore()" obsolete "switch_buffer()" and
"restore_buffer()".
Latter are unused since https://github.com/neovim/neovim/pull/15831.
Mark them as N/A (until some test fails).

Problem: Vim9: has() assumes a feature does not change dynamically.
Solution: Check whether a feature may change dynamically. (closesvim/vim#7265)
----
"dynamic_feature()" is only for vim9script which is N/A.

Note this doesn't find new N/A patches by itself
and this is to align with ':h dev-vimpatch'.
Neovim refactored Vim's "char/string" functions to be either safer
(ie. xstrlcat) or target Unicode.
Note this doesn't find new N/A patches by itself
and this is to align with ':h dev-vimpatch'.
I use the 'vim_na_*' files to debug the filtered diff of files
that seem N/A but contain relevant code.
I can't blacklist the entire file.
Nvim relies on commit history for automated updates
to ported Vim patches across Vim releases via "included_patchsets[]".
Each Vim commit is suppose to manually adjust "included_patches[]"
but it is prone to human error such that vim-patch.sh found
the following N/A commits:
```
495282b6e Correct list of patch numbers
85d9b03f8 Correct list of patches.
```
Prior to this commit, vim-patch doesn't find the following N/A commit:
```
9.0.2172: Vim9: compiling :defer may fail
```
