1204 - Variable '%s' contains %i elements, but loop is for %i elements.
Description
    
A ForEach loop has been defined to loop through several Arrays in parallel, but not all Arrays are of the same size.
    
Example
    
Config:
    .Configs = { 'debug', 'release', 'master' }
.Options = { 'a',     'b' }
ForEach( .Config in .Configs,
         .Option in .Options )
{
}
Output:
c:\Test\fbuild.bff(4):(21) FASTBuild Error #1204 - ForEach() - Variable '.Options' contains 2 elements,
but loop is for 3 elements.
         .Option in .Options )
                    ^
                    \--here
Fix:
.Configs = { 'debug', 'release', 'master' }
.Options = { 'a',     'b',       'c' }
ForEach( .Config in .Configs,
         .Option in .Options )
{
}
