server : change deps.sh xxd files to string literals (#5221)

* Changed ugly xxd to literals.

HPP files are much more readable as multiline literals rather than hex arrays.

* Dashes in literal variable names.

Replace . and - with _ in file names -> variable names.

* Comment on removing xxd.

XXD-> string literals

* XXD to string literals.

Replaced these unreadable headers with string literal versions using new deps.sh.
