Fix createdump failure on MacOS Monterey version 12.0.1.

[mikem8361]

Customer Impact

Customers (like VS4Mac and the dev in the below issue) fail to collect dumps on MacOS Monterey.

Details

Fails looking for the symbol _dyld_all_image_infos in dylinker. The fix is to fallback to searching all the symbols after searching the "external" symbols.

Issue: #62181

Testing

Local testing. The VS4Mac team has verified.

Risk

Low since it only affects createdump and managed debugging (DBI/DAC).
