PA: Fix transitive include of //build/build_config.h

I am investigating why the CQ is blocking:
https://chromium-review.googlesource.com/c/chromium/src/+/5205331?checksRunsSelected=linux-rel&tab=checks

Apparently, some bots on Linux become much slower, causing global
timeout. The patch is a no-op. So I am supposing this is caused by
some missing //build/build_config.h that used to be transitively
included, but aren't after reordering some headers.o

Note: In practise this wasn't the issue. It is still worth fixing.

Script:
-------

```
tokens=$(cat build/build_config.h | sed -n "s/#define \([^\ ()]*\) /\1 /p" | cut -f1 -d\ )

for file in $(find base/allocator/partition_allocator/src/partition_alloc -name "*.h" -o -name "*.cc")
do
  include_line=$(grep -n "build/build_config.h" "$file" | head -1 |cut -f1 -d:)
  for token in $tokens
  do
    token_line=$(grep -n "$token" "$file" | head -1 | cut -f1 -d:)

    if [[ "$token_line" == "" ]]
    then
      continue
    fi

    if [[ "$include_line" == "" ]]
    then
      echo "$file" -- "$token" -- " Missing include"
      continue
    fi

    if [ "$include_line" -gt "$token_line" ]
    then
      echo "$file" -- "$token" -- " Token used before include: $include_line vs $token_line"
    fi
  done
done | sort | uniq -c | sort -rn
```

Output:
-------
```
2 base/allocator/partition_allocator/src/partition_alloc/partition_alloc_base/memory/ref_counted.cc -- ARCH_CPU_X86_FAMILY --  Missing include
1 base/allocator/partition_allocator/src/partition_alloc/partition_alloc_base/memory/ref_counted.cc -- ARCH_CPU_X86 --  Missing include
