13f63010 - Modify dwarfdump verification to allow sub-category counts (#125062)

Modify dwarfdump verification to allow sub-category counts (#125062) It was discovered that BOLT had several distinct issues of missing debug information by various tags for debug names (119493 & 119023 as examples), but the verification of a DWARF with llvm-dwarfdump prior to those fixes only gave one 'missing name' category. ``` {"error-categories":{"Name Index DIE entry missing name":{"count":36355210}},"error-count":36355210} ``` To more easily leverage dwarf verification for debug health, the JSON output will be improved to allow having detailed counts by a sub-category when it makes sense. For now, this is only implemented on the missing tags, but can be extended to more. ``` {"error-categories":{"Name Index DIE entry missing name":{"count":10,"details":{"DW_TAG_inlined_subroutine":1,"DW_TAG_label":1,"DW_TAG_namespace":2,"DW_TAG_subprogram":2,"DW_TAG_variable":4}}},"error-count":10} ``` This diff also modifies the tests created in pull request 124936 (not yet landed) to ensure the JSON switches. Ideally this lands after that but it did not correctly create a stack of pull requests.
