Problem: Vim still supports compiling on NeXTSTEP
Solution: Drop Support (Damien Lejay)
The NeXTSTEP operating system has been obsolete for decades. The
special-case code required to support it adds unnecessary complexity,
preprocessor conditionals, and non-standard workarounds to the codebase.
This commit removes all support for NeXTSTEP, simplifying the code and
build system in several ways:
- Replaced custom configure checks for `union wait` with a standard `AC_CHECK_FUNCS` call for `waitpid`.
- Removed all conditional code that used the non-standard `union wait` for process status, relying solely on a standard `int`.
- Replaced calls to the non-standard `wait4()` function with the POSIX-standard `waitpid()`.
- Cleaned up headers (`os_unix.h`, `os_unixx.h`) to remove NeXT-specific workarounds and macros.
- Removed obsolete NeXT compilation instructions from the INSTALL file.
This change improves maintainability and makes the Unix process handling code more linear and compliant with modern POSIX standards.

Problem: There is no real need for a "big" build.
Solution: Move common features to "normal" build, less often used features
to the "huge" build. (Martin Tournoij, closes#11283)
Problem: Not easy to figure out what packages to get when installing Vim on
a new Ubuntu system.
Solution: Mention explicit commands that are easy to follow.
