sys.path.remove("") raises ValueError if the item is missing.

fixes#11293
compared to vim.api.|nvim_call_function|, this fixes some typing issues
due to the indirect conversion via the API. float values are preserved
as such (fixes#9389) as well as empty dicts/arrays.
Ref https://github.com/norcalli/nvim.lua for the call syntax
In order to find if there was already an open man page, the :Man command
would cycle through each window to see if &ft=='man'. This triggers
autocmds, e.g. BufEnter, unnecessarily and can have unexpected
side-effects.
Change the logic to check each window's ft without switching to it
unless it is actually a man window.

It's a bit cumbersome for us to add an export target every time we define a new function.
It's also cumbersome to care about the order of definition when creating a new function by referring to other functions in the module.
The Python provider was special (via [1]), and would continue to do
checks with `0` being set explicitly even.
This was fixed in #11044 (45447e3b6), ref: #11040.
This extends it to use the same method with all providers.

This reverts part of ade88fe4c [1].
This is required for `let g:python3_host_prog = 'python'` etc, where it
should get picked up from PATH.
Without this it would show:
```
- INFO: pyenv: Path: /home/user/.pyenv/libexec/pyenv
- INFO: pyenv: Root: /home/user/.pyenv
- INFO: Using: g:python3_host_prog = "python"
- ERROR: "python" was not found.
- INFO: Executable: Not found
- ERROR: Detected pip upgrade failure: Python executable can import "pynvim" but not "neovim": python
- ADVICE:
- Use that Python version to reinstall "pynvim" and optionally "neovim".
pip3 uninstall pynvim neovim
pip3 install pynvim
pip3 install neovim # only if needed by third-party software
```
Note that it additionally causes a weird error
("Detected pip upgrade failure"), due to `s:check_bin` emptying
`python_exe` (because the non-absolute file not being readable), and
`provider#pythonx#DetectByModule('pynvim', a:version)` from 75593e6fce
then just getting the value from the host var again (without actual
checks).
This is implicitly fixed via this patch now (because it is skipped), but
could need some improvement in this regard probably.
With this patch it resolves it (for a virtualenv where pynvim is not
made available intentionally):
```

Previously, the "precedes" character would be rendered on every row
when w_skipcol > 0 (i.e., when viewing a single line longer than the
entire screen), instead of just on the first row. Make sure to only
render it on the first row in this case.
Add a test for this behavior.
Fix documentation for the "precedes" character, which erroneously
stated that it was only active when wrap mode was off.
