This CL starts adding the basics for an IR for Tint. The IR is
a lower level representation then the AST with several of the
restrictions removed. For example, the IR is mutable, is a DAG
instead of a tree, and removes a number of WGSL constructs to
simplify transforms.

Attempting to paper over all the MSL standard library holes for packed_vector in the MSL writer added complexity to the writer, produced messy output, and didn't actually catch all the cases where casts were needed.
Add a new PackedVec3 transform that applies the packed_vector -> vec casts in a smarter, more precise way.

This fixes cases where input args of different type are mixed between
constant and runtime evaluated. We initially did this only for builtins
(https://dawn-review.googlesource.com/c/dawn/+/104545) to fix cases like
`select`, but we also need this for binary operators like shift
left/right that also take args of differing types. For consistency, this
change also includes passing in the earliest evaluation stage when
looking up unary ops and initializer/conversions.

Change 104120 enabled `EGL_EXT_create_context_robustness` to ensure that robustness is enabled for OpenGL.
Despite listing `EGL_EXT_create_context_robustness` in the extension list, Nvidia linux drivers will error with `EGL_BAD_ATTRIBUTE` when `EGL_CONTEXT_OPENGL_ROBUST_ACCESS_EXT` is specified when requesting an OpenGL context (ES works fine!)
EGL promoted this extension to core in EGL 1.5, and requesting `EGL_CONTEXT_OPENGL_ROBUST_ACCESS` keeps Nvidia happy - so use this instead.
Note: We already require EGL 1.5 for EGLImage.
