Subject: [PATCH] gl_resource_manager: Make use of noexcept on move assignment
 and move constructors

Several standard constructors generally check if objects can be moved in
a non-throwing manner (usually via std::move_if_noexcept) to preserve
its exception guarantees. This means that if these were used with
certain containers any reallocations internally would cause resource
churn, as copies would be necessary instead of moves.

This way, if they're every used in that manner, the right behavior is
always performed.
