Dmitrii Kuvaiskii f2f83aa2b5 [Pal/Linux-SGX] Use hard-coded SSA frame size equal to 4 pages ...

Previously, the SGX-signing Python script had a hard-coded value of
1 page. However, the Linux-SGX runtime calculated the SSA frame size
based on the information from CPUID and XFRM. The SSA frame size is
a total of XSAVE area size + GPRs + MISC region, and on feature-rich
CPUs may exceed 1 page. Thus, the SSA frame size in the SIGSTRUCT
(during SGX signing) and in the SECS (during runtime) may mismatch on
such CPUs, and EINIT fails with SGX_INVALID_MEASUREMENT. This commit
simply hard-codes SSA frame size to overapproximated value of 4 pages.
