selftests/x86/lam: Add ARCH_FORCE_TAGGED_SVA test cases for linear-address masking
By default do not allow to enable both LAM and use SVA in the same
process.
The new ARCH_FORCE_TAGGED_SVA arch_prctl() overrides the limitation.
Add new test cases for the new arch_prctl:
Before using ARCH_FORCE_TAGGED_SVA, should not allow to enable LAM/SVA
coexisting. the test cases should be negative.
The test depands on idxd driver and iommu. before test, need add
"intel_iommu=on,sm_on" in kernel command line and insmod idxd driver.
