[Vulkan] Merge upsample_nearest2d and quantized_upsample_nearest2d (#97467)
Summary: Merging quantized_upsample_nearest2d into upsample_nearest2d. Therefore, at::upsample_nearest2d can handle quantized vulkan input tensors.
Test Plan:
On Mac
```
cd ~/fbsource
buck1 run -c pt.vulkan_full_precision=1 //xplat/caffe2:pt_vulkan_quantized_api_test_binAppleMac\#macosx-arm64
```
On Android
```
cd ~/fbsource
buck1 build -c ndk.custom_libcxx=false -c pt.enable_qpl=0 -c pt.vulkan_full_precision=1 //xplat/caffe2:pt_vulkan_quantized_api_test_binAndroid\#android-arm64 --show-output
adb push buck-out/gen/xplat/caffe2/pt_vulkan_quantized_api_test_binAndroid\#android-arm64 /data/local/tmp/vulkan_quantized_api_test
adb shell "/data/local/tmp/vulkan_quantized_api_test"
```
