Enable a set of config related to kernel trust, including
vptm, IMA, EVM, smack LSM, and SM3, SM4, in which SM algorithm
is compiled into module.

These configs also support the x64 arm platform.

The following are some performance data. The output of
`systemd-analyze` on the startup time of an ECS (executed
three times):

before:
725ms (kernel) + 471ms (initrd) + 3.375s (userspace) = 4.572s
794ms (kernel) + 426ms (initrd) + 3.281s (userspace) = 4.501s
797ms (kernel) + 464ms (initrd) + 3.275s (userspace) = 4.538s

after:
777ms (kernel) + 439ms (initrd) + 3.456s (userspace) = 4.672s
785ms (kernel) + 450ms (initrd) + 3.313s (userspace) = 4.549s
741ms (kernel) + 481ms (initrd) + 3.274s (userspace) = 4.497s
