Ben Clayton 2da833d815 writer: Simplify floats when printed
Add `tint::writer::FloatToString()`:

Converts the float `f` to a string using fixed-point notation (not scientific).
The float will be printed with the full precision required to describe the float.
All trailing `0`s will be omitted after the last non-zero fractional number,
unless the fractional is zero, in which case the number will end with `.0`.

Use this for the wgsl, msl and hlsl backends.

Ben Clayton 4bfe461646 Big cleanup now that AST nodes are raw pointers
Remove all redundant std::move()s. I've also removed calls to
std::move() in tests, even if they act as an optimization. This is for
two reasons:
(a) Performance is not important for testing, and this helps with
    readability.
(b) A whole bunch tests were relying on std::move() clearing vectors so
    they can be repopulated and used again. This is undefined behavior:

> Objects of types defined in the C++ standard library may be moved from
> (12.8). Move operations may be explicitly specified or implicitly
> generated. Unless otherwise specified, such moved-from objects shall
> be placed in a valid but unspecified state.

All of these UB cases have been fixed.

Removed all duplicate variables left over from:
  `auto* foo_ptr = foo.get()`
which became:
  `auto* foo_ptr = foo`

`StructDecoration` has been transformed from an `enum class` to a proper class so it can derive from `Decoration`.
