Formatting cmake (to lowercase without space for if/elseif/else/endif) (pytorch#35521)

Summary:
Running commands:
```bash
shopt -s globstar

sed -e 's/IF (/if(/g' -e 's/IF(/if(/g' -e 's/if (/if(/g' -e 's/ELSE (/else(/g' -e 's/ELSE(/else(/g' -e 's/else (/else(/g' -e 's/ENDif(/endif(/g' -e 's/ELSEif(/elseif(/g' -i CMakeLists.txt

```
We may further convert all the commands into lowercase according to the following issue: https://gitlab.kitware.com/cmake/cmake/commit/77543bde41b0e52c3959016698b529835945d62d.
