[4/n] Update vulkan test path (#62519)
Summary:
Fixes https://github.com/pytorch/pytorch/issues/62380
* update `test_vulkan` function to call wheel install folder {sitepackages}/torch instead of build/ folder
* add `IN_WHEEL_TEST` to limit the change for `pytorch_linux_test` only
* add symbolic link for shared libraries which are called by the tests (this is a bit hacky and should be fixed the rpath before compiling -- similar to https://github.com/pytorch/pytorch/blob/master/.jenkins/pytorch/test.sh#L204-L208).
