CC3220SF_LAUNCHXL: keep ulDebugHeader symbol in LTO builds 

Add a "used" attribute to ulDebugHeader (placed in signature_section section)
to fix ARMC6 build with the "-flto" flag. (Error: L6236E: No section matches
selector - no section to be FIRST/LAST. )

This attribute, attached to a function, means that code must be emitted
for the function even if it appears that the function is not referenced.
