- Remove Types variant, and replace with a type-erasing Value class
instead. This is not only better for compile times, but makes the code
much easier to understand.
- Value wraps an internal shared_ptr to a const detail::ValueBase,
allowing it to be used as a value-type (i.e. copyable), while behaving
polymorphically.
- Add static_asserts to Val, Vec, and Mat creation helpers to emit a
more useful error message when the wrong type is passed in.

For example, a large f32 value converted to f16 now fails, instead of
resulting in +/-inf.

The reason for slow compile times is because the very large variants of
builder::Value<T>s combined with the many std::visits over these
variants result in many combinatorial instantiations of the visit
callbacks.
To address this, I added a polymorphic base class ValueBase to Value<T>,
and replaced most of the std::visit-based compile time code with runtime
virtual calls. For the two heaviest users of std::visit over the large
variants, compiles times dropped more than half (clang-10, debug):
const_eval_binary_op_test.cc: 19.079s to 7.736s
const_eval_unary_op_test.cc: 10.021s to 4.789s

The single file was taking too long to compile, and was becoming
difficult to work in.
