[vector] Disallow accidental creation of transient vectors
Fix sites that were doing this under our feet.
This lowers precision of some instancing operations from double

Fix IUP differences accoss platforms.
- Slightly increase the tolerance to account for differences in floating point math across platforms.
- The specific issue is a fused multiply add (d = d1 + (x - x1) * scale; in hb-subset-instancer-iup.cc)
- Also fix more implicit double conversion warnings.

[instancer] templatize the priority queue, use custom type for varstore
when instantiating varstore, we need to pop a tuple like
(combined_gain, i, j), if combined gain is the same then we compare the
value of i, and then j. So we'd like to use custom type as the key when
popping from the queue. This would match fonttool's algorithm cause it
uses heappop().

Specify tuple_variations_t special member functions
Building with clang complains about the use of `tuple_variations_t`'s
implicit copy constructor and copy assignment operator, since automatic
generation of these is deprecated when declaring a non-default
destructor. This is a good warning because it isn't obvious that copies
were being made instead of the object being moved and this struct should
be moved and not copied. Declare all the special member functions,
defaulting the moves and deleting the copies.
After making `tuple_variations_t` move only, an issue is revealed in
`hb_vector_t::push` which has been requiring that objects be copyable.
Remove the old non-emplacing `push` now that this works with all
existing objects and make a single `push` which is more like
`std::vector::emplace_back` since that is somewhat what the newer `push`
is attempting to do.
