writer/hlsl: Rework string printing

Remove `pre` and `out` parameters from most generator methods.
Use the `out_` string stream in TextGenerator, add helpers to TextGenerator to simplify line printing.

Remove the `pre` and `out` fields from TestHelper.

Cleans up the `pre` aspects of the HLSL writer, so the same concept can be used by the MSL writer.
Fixes indentation bugs in formatting.
