x86/its: explicitly manage permissions for ITS pages
execmem_alloc() sets permissions differently depending on the kernel
configuration, CPU support for PSE and whether a page is allocated
before or after mark_rodata_ro().
Add tracking for pages allocated for ITS when patching the core kernel
and make sure the permissions for ITS pages are explicitly managed for
both kernel and module allocations.
Fixes: 872df34d7c51 ("x86/its: Use dynamic thunks for indirect branches")
