This PR brings best practices mentioned to me on other prs and adds them
to the existing builtin tests.
Note to reviewers: I put this up in two commits because the clang-format
changes is making it hard to tell what actually changed.
use the first commit to check for correctness.
We previously made an implmenetation error when adding `half` overloads
for HLSL library functionalitly. The `half` type is always defined in
HLSL and `half` intrinsics should not be conditionally included.
When native 16-bit types are disabled `half` is a unique 32-bit float
type with lesser promotion rank than `float`.
Fixes#81049
short will be promoted to int in UsualUnaryConversions.
Disable it for HLSL to keep int16_t as 16bit.

Should have done this from the start. Since all the injected AST types
are in the hlsl namespace we should also put the header-defined types
and functions in there too.
This updates the basic_types test to run once with the namespaced types
and once without, and adds using declarations or namespaces calls in
other tests.

Add vector version of abs as
```
__attribute__((clang_builtin_alias(__builtin_elementwise_abs)))
int2 abs (int2 );
__attribute__((clang_builtin_alias(__builtin_elementwise_abs)))
int3 abs (int3 );
```
To make this work.
Allowed custom type checking builtins to be recelareable.
