spirv: lower air try 
Implements code generation for the try air tag. This commit also adds
a utility `errorUnionLayout` function that helps keeping the layout
of a spir-v error union consistent.

spirv: fix OpFunctionCall parameters interleaving with insts 
resolve() is now able to emit instructions. If usage of this function is
interleaved with calls to emitRaw() and writeOperand(), then an
instruction may get inserted between operands, causing an invalid module.
The solution here is to just perform a temporary allocation.

spirv: fix use-after-realloc in resolveType() 
The pointer to a slot in a hash map was fetched before a recursive call.
If the hash map's size changed during the recursive call, this would write
to an invalid pointer.

The solution is to use an index instead of a pointer. Note that care must be
taken that resolved types (from the type_cahce) must not be accessed, as they
might be incomplete during this operation.

```
This is only noticed in a debug build of zig and silently does the wrong
thing and overflows in release builds.

This happened to `[x]u65529` and above because of the ` + 7` on a `u16`.
