mongodb: Backport fix for SERVER-49099

The Node and Head swap() friends and the copy-and-swap assignment
operators in Biggie store.h are unused and refer to members that do
not exist. Backport the upstream removal.

+Subject: [PATCH] SERVER-49099 Remove the Node::swap() function in Biggie
+
+The Node and Head swap() friends and the copy-and-swap assignment
+operators built on them are unused and do not compile: Node::swap()
+does not exist and Node has no trieKey, depth, data or children
+members (they are _-prefixed). This went unnoticed because they are
+in a class template that never instantiates them.
+
+Upstream-Status: Backport [https://github.com/mongodb/mongo/commit/77ffbcb4f5673b154fe64872cba9f34ce97bc55d]
