Add `cetl::pf17::uninitialized_move` in `cetl/pf17/memory.hpp`, with standard move semantics, exact cleanup of successfully constructed destination objects on failure, and caller-owned storage.\n\nFollow the existing pf17 header, namespace, Doxygen, exception-guard, and facade conventions. `cetl::uninitialized_move` selects the polyfill in C++14 and the standard implementation in C++17 and newer. An internal construction/rollback helper accepts construction and destruction callbacks for subsequent allocator-aware VLA integration. It records each successful construction before advancing the input iterator, so an iterator exception also destroys the most recently constructed object.\n\nThis branch is based directly on `main`, independently of #207 and #208. VLA integration remains in #37.\n\nCloses #206.\n\nValidation:\n- Dedicated CETLVaSt tests cover empty/single/multiple elements, move-only and copy-only values, nontrivial lifetimes, single-pass input and forward destination iterators, construction and input-iterator failures, original exception propagation, overloaded address-of, and class-specific placement new. Success and construction-failure cases also run against the standard algorithm in C++17 and newer.\n- GCC 13.4 and Clang 22.1.8: C++14/17/20/23, each in Debug, Release, DebugEP, and ReleaseEP (32 passing configurations, including exceptions disabled).\n- Clang C++14 ASan/UBSan: all 17 tests pass.\n- Existing C++14 string-view and memory-resource suites: all 65 tests pass.\n- Formatting and `git diff --check` pass
