[llvm] [llvm][Object] Add missing const qualifier for value_type in content_iterator (PR #124106)

[Bushev Dmitry via llvm-commits]

https://github.com/dybv-sc created https://github.com/llvm/llvm-project/pull/124106

value_type was defined as non-const for content_iterator, although it's methods returned a const pointers/references. This prevented it from using in some algorithms from STLExtras.h
