  [llvm-readobj][ELF] Implement JSON output for --dynamic-table (#95976)

When printing JSON output with --dynamic-table I noticed that the output
is invalid JSON. This patch overrides the printDynamicTable() function
in the JSONELFDumper to return a list of dictionaries for the
DynamicSection value.
Before the output was:
```
 {
    "FileSummary": {
      "File": "bin/llvm-readelf",
      "Format": "elf64-x86-64",
      "Arch": "x86_64",
      "AddressSize": "64bit",
      "LoadName": "<Not found>"
    }DynamicSection [ (35 entries)
  Tag                Type         Name/Value
  0x000000000000001D RUNPATH      Library runpath: [$ORIGIN/../lib:]
  0x0000000000000001 NEEDED       Shared library: [libm.so.6]
  0x0000000000000001 NEEDED       Shared library: [libz.so.1]
  0x0000000000000001 NEEDED       Shared library: [libzstd.so.1]
```
Now the output looks like:
```
 "DynamicSection": [
      {
        "Tag": 29,
        "Type": "RUNPATH",
        "Value": 6322,
        "Path": [
          "$ORIGIN/../lib"
        ]
      },
      {
        "Tag": 1,
        "Type": "NEEDED",
        "Value": 6109,
        "Library": "libm.so.6"
      },
```
