qapi: make SGX commands unconditionally available

This removes the TARGET_I386 condition from the SGX confidential
virtualization commands, moving them to the recently introduced
misc-i386.json QAPI file, given they are inherantly i386 specific
commands.

Observe a pre-existing bug that the "SGXEPCSection" struct lacked
a TARGET_I386 condition, despite its only usage being behind a
TARGET_I386 condition.
