Problem:
There are three different ways of marking an option as hidden, `enable_if
= false`, `hidden = true` and `immutable = true`. These also have different
behaviors. Options hidden with `enable_if = false` can't have their value
fetched using Vim script or the API, but options hidden with `hidden = true` or
`immutable = true` can. On the other hand, options with `hidden = true` do not
error when trying to set their value, but options with `immutable = true` do.
Solution:
Remove `enable_if = false`, remove the `hidden` property for options, and use
`immutable = true` to mark an option as hidden instead. Also make hidden option
variable pointers always point to the default value, which allows fetching the
value of every hidden option using Vim script and the API. This does also mean
that trying to set a hidden option will now give an error instead of just being
ignored.
Problem: filetype: some requirements files are not recognized
Solution: Detect '*-requirements.txt', 'constraints.txt',
'requirements.in', 'requirements/*.txt' and 'requires/*.txt'
as requirements filetype, include pip compiler, include
requirements filetype and syntax plugin

Solution: set LC_ALL=C
fix: make test_compiler failed on xubuntu 22.04.3
Problem: 'make test_compiler' failed on Linux xubuntu 22.04.3 but
succeeded on e.g. macOS. To reproduce:
```
$ ./configure --with-features=huge --enable-gui=no --enable-perlinterp=yes
$ make -j12
$ cd vim/src/testdir
$ make test_compiler
...snip...
Found errors in Test_compiler():
