[Issue 11789](https://d.puremagic.com/issues/show_bug.cgi?id=11789)
std.algorithm: Fix the hasAssignableElements restriction from HeapSort

This restriction seems unnecessary (as HeapSortImpl uses swap/swapAt,
which does not require assignability), and was getting in the way of
e.g. sorting a range of Refs. The range can satisfy either
hasAssignableElements, or hasSwappableElements
Add notes to Splitter docs
Switch to matchFirst/matchAll for examples
Use documented unittest rather than code dup
std.algorithm: Allow proxySwap-using swap overload to take by ref
std.algorithm: Add test for sorting via proxySwap
std.variant: Adjust test for ARM
