### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #xxx
Problem Summary:
Doris does not have a native UUID SQL and storage type, so UUID values must
be stored as strings and cannot use a fixed-width representation or UUID-aware
generation and version functions. Add a native 128-bit UUID type across FE, BE,
IDL, storage, serialization, expressions, runtime filters, external and JNI
bridges, and schema metadata. Accept canonical and compact hexadecimal input,
normalize output to lowercase canonical form, preserve unsigned canonical
ordering, and add native UUID v4 and v7 generation and version inspection while
keeping the existing string-returning uuid() behavior compatible.
