Set misc_attr in the top level sgx_create_enclave if _create_enclave
fails. This provides the user with the platform's capabilities when
sgx_create_enclave fails for any reason other than a parameter error.
Previously the misc_attr was only set upon failure if build_image
failed, which was not helpful when sgx_create_enclave failed due to
an attribute error, e.g. misc_select, as the flow aborted before it
reached build_image.

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.
