Move the implementation of skeleton PAL V2 APIs from liberpal-skeleton-v2.c
to liberpal-skeleton.c
Signed-off-by: NYilin Li <YiLin.Li@linux.alibaba.com>

Since the pal_create_process interface of PAI API v2 has achieved a similar function, fork-test argument is useless.

There are still lots of SGX1 machines without FLC support deployed
in filed. These machines eventually needs to be migrated to be supported
by SGX in-tree driver which is product-ready and well-maintained.

This patch targets to address the gap between SGX1 machine and SGX
in-tree driver.

SGX in-tree driver has a different way to go agains SGX out-of-tree
driver. The enclave range is mapped to EPC memory after executing
EINIT, so the anonymous mapping occupying enclave range must be done
early instead of creating it based on the fd of /dev/isgx.
