Add CMake build system for valkey (#1196)
With this commit, users are able to build valkey using `CMake`.

## Example usage:

Build `valkey-server` in Release mode with TLS enabled and using
`jemalloc` as the allocator:

```bash
mkdir build-release
cd $_
cmake .. -DCMAKE_BUILD_TYPE=Release \
         -DCMAKE_INSTALL_PREFIX=/tmp/valkey-install \
         -DBUILD_MALLOC=jemalloc -DBUILD_TLS=1
make -j$(nproc) install

# start valkey
/tmp/valkey-install/bin/valkey-server
```

Build `valkey-unit-tests`:

```bash
mkdir build-release-ut
cd $_
cmake .. -DCMAKE_BUILD_TYPE=Release \
         -DBUILD_MALLOC=jemalloc -DBUILD_UNIT_TESTS=1
make -j$(nproc)

# Run the tests
./bin/valkey-unit-tests 
```

Current features supported by this PR:

- Building against different allocators: (`jemalloc`, `tcmalloc`,
`tcmalloc_minimal` and `libc`), e.g. to enable `jemalloc` pass
`-DBUILD_MALLOC=jemalloc` to `cmake`
- OpenSSL builds (to enable TLS, pass `-DBUILD_TLS=1` to `cmake`)
- Sanitizier: pass `-DBUILD_SANITIZER=<address|thread|undefined>` to
`cmake`
- Install target + redis symbolic links
- Build `valkey-unit-tests` executable
- Standard CMake variables are supported. e.g. to install `valkey` under
`/home/you/root` pass `-DCMAKE_INSTALL_PREFIX=/home/you/root`

Why using `CMake`? To list *some* of the advantages of using `CMake`:

- Superior IDE integrations: cmake generates the file
`compile_commands.json` which is required by `clangd` to get a compiler
accuracy code completion (in other words: your VScode will thank you)
- Out of the source build tree: with the current build system, object
files are created all over the place polluting the build source tree,
the best practice is to build the project on a separate folder
- Multiple build types co-existing: with the current build system, it is
often hard to have multiple build configurations. With cmake you can do
it easily:
- It is the de-facto standard for C/C++ project these days

More build examples: 

ASAN build:

```bash
mkdir build-asan
cd $_
cmake .. -DBUILD_SANITIZER=address -DBUILD_MALLOC=libc
make -j$(nproc)
```

ASAN with jemalloc:

```bash
mkdir build-asan-jemalloc
cd $_
cmake .. -DBUILD_SANITIZER=address -DBUILD_MALLOC=jemalloc 
make -j$(nproc)
```

As seen by the previous examples, any combination is allowed and
co-exist on the same source tree.

## Valkey installation

With this new `CMake`, it is possible to install the binary by running
`make install` or creating a package `make package` (currently supported
on Debian like distros)

### Example 1: build & install using `make install`:

```bash
mkdir build-release
cd $_
cmake .. -DCMAKE_INSTALL_PREFIX=$HOME/valkey-install -DCMAKE_BUILD_TYPE=Release
make -j$(nproc) install
# valkey is now installed under $HOME/valkey-install
```

### Example 2: create a `.deb` installer:

```bash
mkdir build-release
cd $_
cmake .. -DCMAKE_BUILD_TYPE=Release
make -j$(nproc) package
# ... CPack deb generation output
sudo gdebi -n ./valkey_8.1.0_amd64.deb
# valkey is now installed under /opt/valkey
```

### Example 3: create installer for non Debian systems (e.g. FreeBSD or
macOS):

```bash
mkdir build-release
cd $_
cmake .. -DCMAKE_BUILD_TYPE=Release
make -j$(nproc) package
mkdir -p /opt/valkey && ./valkey-8.1.0-Darwin.sh --prefix=/opt/valkey  --exclude-subdir
# valkey-server is now installed under /opt/valkey

```
