[MERGE chakra-core#5583 @rhuanjl] Add end of file new line check fix chakra-core#496

Merge pull request chakra-core#5583 from rhuanjl:endOfFile

Per issue chakra-core#496 augment the existing line ending check to also check to ensure that each file ends in a newline.

Note, per logic in check_eol.sh this test is run only on:
1. Files edited in the current PR
2. Files that are not JS test files OR any cmd, baseline, wasm, vcxproj or sln files

Also note:
1. As this runs only on files edited din current PR it won't catch any historic mistakes
2. It doesn't check JS test files - this seemed odd to me but chose to leave it
