Clamp clear color value to legal range for uint/sint formats

This patch clamps GPURenderPassColorAttachment.clearValue into the
legal range for uint/sint formats according to the latest WebGPU
SPEC.

This patch also adds tests to verify we can directly apply floating
point clear values for normalized floating formats.

We don't handle non-normalized floating formats as the exact choice
of the converted value is implementation-defined.
