x86/sgx: Rename sgx_encl_ewb_cpumask() as sgx_encl_cpumask()
sgx_encl_ewb_cpumask() is no longer unique to the reclaimer where it
is used during the EWB ENCLS leaf function when EPC pages are written
out to main memory and sgx_encl_ewb_cpumask() is used to learn which
CPUs might have executed the enclave to ensure that TLBs are cleared.
Upcoming SGX2 enabling will use sgx_encl_ewb_cpumask() during the
EMODPR and EMODT ENCLS leaf functions that make changes to enclave
pages. The function is needed for the same reason it is used now: to
learn which CPUs might have executed the enclave to ensure that TLBs
no longer point to the changed pages.
Rename sgx_encl_ewb_cpumask() to sgx_encl_cpumask() to reflect the
broader usage.
