55a2c3095d [naga] Support textureSampleBaseClampToEdge() for texture2d 
Adds a new flag to the IR indicating when image sample coordinates are
to be clamped. Adds wgsl-in support for parsing and lowering to
IR. Validation ensures this flag is only used when sampling a 2D
non-arrayed sampled texture, without offset, gather, or depth
comparison. This matches the WGSL requirements, with the exception of
supporting `texture_external` textures, which will follow in a later
patch.

SPIRV, HLSL, and Metal backends are supported so far, with GLSL left
for a follow up. (In GLSL the texture will simply be sampled without
the coordinates being clamped.)

It may seem unfortunate to have to handle this separately for each
backend, and indeed it would have been possible to implement this simply
in the WGSL frontend. However, future patches will add support for using
textureSampleBaseClampToEdge() with external textures, which will
actually have to be handled by each backend. This patch is laying the
groundwork for that.

91e4be314c [naga doc] Fix broken links in Naga bitflags types. 
Fix links in documentation for types defined using the `bitflags!` macro.

As described in [bitflags#407], for some reason, `cargo doc` doesn't
check for broken links in documentation for types or members defined
using `bitflags::bitflags!`.

9f91c95c24 [naga] Introduce Scalar type to IR. 
Introduce a new struct type, `Scalar`, combining a `ScalarKind` and a
`Bytes` width, and use this whenever such pairs of values are passed
around.

In particular, use `Scalar` in `TypeInner` variants `Scalar`, `Vector`,
`Atomic`, and `ValuePointer`.

Introduce associated `Scalar` constants `I32`, `U32`, `F32`, `BOOL`
and `F64`, for common cases.

Introduce a helper function `Scalar::float` for constructing `Float`
scalars of a given width, for dealing with `TypeInner::Matrix`, which
only supplies the scalar width of its elements, not a kind.

Introduce helper functions on `Literal` and `TypeInner`, to produce
the `Scalar` describing elements' values.

Use `Scalar` in `wgpu_core::validation::NumericType` as well.
