Fred Grim ab930ee7ca [llvm-readobj][ELF] Alter JSON/LLVM output on note sections to allow for multiple notes per section in JSON (#96813)
It turns out that the notes section for corefiles (or really any elf
file with multiple notes) is set up in such a way for LLVM formatted
output that the JSON equivalent only has the last note since the notes
are held in a dictionary with every key being Note. This pr alters the
layout for the notes to a list of dictionaries to sidestep this issue
for JSON output. Prior to this pr a note section in the output looked
like (for LLVM output):

```
Notes [
  NoteSection {
    Name: <?>
    Offset: 0x2148
    Size: 0x1F864
    Note {
      Owner: CORE
      Data size: 0x150
      Type: NT_PRSTATUS (prstatus structure)
      Description data (
        0000: 06000000 00000000 00000000 06000000  |................|
        ...
      )
    }
    Note {
      Owner: CORE
      Data size: 0x88
      Type: NT_PRPSINFO (prpsinfo structure)
      Description data (
        0000: 02440000 00000000 04054040 00000000  |.D........@@....|
	....
```

But is now:

```
NoteSections [
  NoteSection {
    Name: <?>
    Offset: 0x2148
    Size: 0x1F864
    Notes [
      {
        Owner: CORE
        Data size: 0x150
        Type: NT_PRSTATUS (prstatus structure)
        Description data (
          0000: 06000000 00000000 00000000 06000000  |................|
          ...
        )
      }
      {
        Owner: CORE
        Data size: 0x88
        Type: NT_PRPSINFO (prpsinfo structure)
        Description data (
          0000: 02440000 00000000 04054040 00000000  |.D........@@....|
	  ...
```
