Replace old-school cmake with the so-called "Modern CMake", meaning
preferring using targets and properties over directory settings and
variables. This allows greater flexibility, robustness and clarity over
how the code works.
The following deprecated commands will be replaced with their modern
alternatives that operates on a specific target, rather than all targets
in the current directory:
- add_compile_options -> target_compile_options
- include_directories -> target_include_directories
- link_libraries -> target_link_libraries
- add_definitions -> target_compile_definitions
There are mainly four main targets that we currently use: nvim, libnvim,
nvim-test (used by unittests) and ${texe} (used by
check-single-includes). The goal is to explicitly define the
dependencies of each target fully, rather than having everything be
dependent on everything else.
Problem: With a long running Vim the temp directory might be cleared on
some systems.
Solution: Lock the temp directory. (closesvim/vim#6044)

This was previously disabled due to build issues on windows.
Any reasonable platform can now be expected to have the necessary
interfaces to build and run the TUI subsystem.
Runtime quality issues of using the TUI (on any new platform) are not
relevant here. Just run Nvim in an external UI instead of the TUI as always.
Problem: Some source files are too big.
Solution: Move buffer and window related functions to evalbuffer.c and
evalwindow.c. (Yegappan Lakshmanan, closesvim/vim#4898)

Allow Include What You Use to remove unnecessary includes and only
include what is necessary. This helps with reducing compilation times
and makes it easier to visualise which dependencies are actually
required.
Work on https://github.com/neovim/neovim/issues/549, but doesn't close
it since this only works fully for .c files and not headers.
Problem:
Dirs "config", "packaging", and "third-party" are all closely related
but this is not obvious from the layout. This adds friction for new
contributors.
Solution:
- rename config/ to cmake.config/
- rename test/config/ to test/cmakeconfig/ because it is used in Lua
tests: require('test.cmakeconfig.paths').
- rename packaging/ to cmake.packaging/
- rename third-party/ to cmake.deps/ (parallel with .deps/)
