ConstNode: Optimize indexes

[sunag]

Description

Added optimization to constants, which now prioritizes the output type if the values ​​are primitive. Previously it was mandatory to use uint() for indexes like .element( uint( 1 ) ) for this optimization, after this PR the conversion is done automatically.

// TSL
cameraProjectionMatrix.element( 2 ).element( 3 ) // 1
cameraProjectionMatrix.element( uint( 2 ) ).element( uint( 3 ) ) // 2

// WGSL - Before
render.cameraProjectionMatrix[ u32( 2.0 ) ][ u32( 3.0 ) ] // 1
render.cameraProjectionMatrix[ 2u ][ 3u ] // 2

// WGSL - Now
render.cameraProjectionMatrix[ 2u ][ 3u ] // 1
render.cameraProjectionMatrix[ 2u ][ 3u ] // 2
