Rewrite vector<T*> into vector<raw_ptr<T, VectorExperimental>>

Code review:
- First patch: Automatic rewrite
- Later patches: Manual fixes

The automatic rewrite used the script:
./tools/clang/rewrite_templated_container_fields/rewrite-multiple-platforms.sh

Binary size increase:
The increase is only 33% (+5kB) above the per-patch limit (+16kB). This
is not a lot given the size of the rewrite. Increase of around 500kb was
approved for MiraclePtr.

AX-Relnotes: n/a.
Binary-Size: See commit description.
