ci: adds flag -Werror=reorder for arm target (#5540)

## Issue being fixed or feature implemented
The order of members in a class/struct definition and the order of their
initialization should match. This ensures that the code is more
error-proof in cases where the order of member initializations is
important, as they may depend on each other.


Instead manual checking of member initialization better let CI handle
it.

#5531 (comment)

## What was done?
New flag "-Werror=reorder" for `configure.ac` and fixes existing code.

## How Has This Been Tested?
Build code with `--enable-werror`



## Breaking Changes
N/A
