Follows up on 590856d (removing the Linux LE).
Removes all of whitelist management and LE facilities from the AESM and SDK.
Leaves only skeleton API stubs behind (for partial ABI compatibility).
!BREAKING CHANGES!
- Launch-related stub(`libsgx_launch.so`) and simulation (`libsgx_launch_sim.so`) libraries
removed from the SGX SDK.
- Removed AESM support for the deprecated Linux SGX out-of-tree (OOT) driver
(will no longer attempt an enclave load if OOT driver is detected)
- AESM APIs for launch control and whitelist management will now
return SGX_ERROR_FEATURE_NOT_SUPPORTED:
Affected APIs:
* get_launch_token(...)
* sgx_get_whitelist_size(...)
* sgx_get_whitelist(...)
* sgx_register_wl_cert_chain(...)
- Deprecated `sgx_uae_launch.h` SDK header
- Marked init token inputs `reserved` in the relevant loader APIs (no longer in use)
