[bug] Issue in TornadoVM-Ray-Tracer with SPIR-V in the JDK 22 branch

[stratika]

Describe the bug

I tried the experimental branch of TornadoVM and JDK 22 with TornadoVM-Ray-Tracer, and I noticed a problem for the SPIR-V backend.

How To Reproduce

I have built TornadoVM as follows:

git checkout feat/jdk22_2nd_iteration
rm -rf graalJars/
./bin/tornadovm-installer --jdk jdk-22 --backend spirv && source setvars.sh

There is a first issue when building the spirv backend:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.11.0:compile (default-compile) on project tornado-drivers-spirv: Compilation failure
[ERROR] /home/thanos/repositories/TornadoVM-stratika/tornado-drivers/spirv/src/main/java/uk/ac/manchester/tornado/drivers/spirv/graal/SPIRVStamp.java:[138,83] error: incompatible types: ResolvedJavaType cannot be converted to JavaKind

I did a small patch, to resolve the fromResolvedJavaType method, similar to the way it is in the other two backends, which you can apply, as follows:
JDK22_SPIRV.txt

git apply JDK22_SPIRV.txt
make BACKEND=spirv

tornado --version

returns

version=1.0.7-dev
branch=feat/jdk22_2nd_iteration
commit=dec5a87

Backends installed: 
	 - spirv

I checked out at the TornadoVM-Ray-Tracer branch and set the variables to use the JDK 22 as JAVA_HOME:

git checkout integration/jdk22
mvn clean install

Then I ran the ray tracer with the regression parameter (in console), and got the output as follows:
