Fix ShaderStorageBlockOutputHLSL::writeEOpIndexDirectOrIndirectOutput https://chromium-review.googlesource.com/c/1304017 removed str() wrapping values passed to TInfoSinkBase::operator<<(). This broke ANGLE roll https://chromium-review.googlesource.com/c/chromium/src/+/1309331 failing compile on linux-libfuzzer-asan-rel bot. Looks like libfuzzer compiler has a bug, not being able to find sh::BlockLayoutEncoder::BytesPerComponent. Wrapping it in str() works around this.
