  -----------
  [clang]Fix Handle structs exceeding 1EB size limit (#146032)

When declaring multiple arrays of 1 ExaByte in a struct, the offset can
exceed 2EB, causing incorrect struct size reporting (only 1EB). This fix
ensures an error is thrown, preventing the generation of incorrect
assembly. #60272
