The signing tool parses values in the enclave configuration as 32-bit
integers. This patch changes it to parse them as 64-bit integers, so
that it can process larger enclaves. This only affects properties such
as MaxStackSize and MaxHeapSize, while subsequent 32-bit bookkeeping,
such as TCSPolicy, MiscSelect, and MiscMask are unchanged.

The urts library and the signing tool often shift page counts as
32-bit integers, then passes the result as a 64-bit value. This patch
casts page counts into 64-bit integers first, so that large page
counts don't overflow.
