LOG: [MemProf] Fix summary bitcode record description (NFC) (#139127)

Commit 776476c282bca71d5b856e80e0a88fbd6f3ccdd2 (PR117404), which
introduced the radix tree representation of allocation context summary
records, incorrectly changed the description of the
FS_COMBINED_CALLSITE_INFO record instead of the intended
FS_COMBINED_ALLOC_INFO record.
