Transpiler - Double Type Conversion

[cmhhelgeson]

Description

For some data types (int, uint), the transpiler unnecessarily converts the GLSL code into node output that converts the type of the variable twice.

Reproduction steps

1. Create an integer or unsigned integer variable on the webgpu_tsl_transpiler example.

It is possible to do some optimizations manually, but we need a flow control for the transpiler, like TSL has, to do it in a more robust way. If we do it in TSL like:

const v = int( int( int( 1 ) ) ).toVar( 'v' );

The result in WGSL will be:

var v : i32;

v = 1;
