tint/writer/glsl: Set default precision to highp
...
WGSL states that `f32` is a IEEE-754 binary32. mediump precision guarantees are much smaller than highp, and using mediump can break code generated by tint.

tint/intrinsics: Texture queries now return unsigned integer / vectors
...
To match the spec.
Also add a bunch of missing texture test cases to
src/tint/ast/builtin_texture_helper_test.cc. Fix all the tests that were
broken because these were not being exercised.
Fixed: tint:1526

GLSL writer: emit gl_PointSize = 1 in all vertex shaders for OpenGL.
...
The OpenGL ES 3.1 spec says:
"The point size is taken from the shader built-in gl_PointSize written by the vertex shader, and clamped to the implementation-dependent point size range. If the value written to gl_PointSize is less than or equal to zero, or if no value is written, the point size is undefined."
ANGLE/D3D11 will emit a warning on this and abort processing, causing dawn_end2end tests to fail.
