Stephen White 790e4c2d60 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.

James Price 3b671cb377 wgsl: Separate struct members with commas 
Use of semicolons is still supported, but deprecated.

Also updates the parsing methods for structures to better match the
WGSL grammar.
