EmulatorPkg: Add CI build for SECURE_BOOT_ENABLE

https://bugzilla.tianocore.org/show_bug.cgi?id=2979



Add EmulatorPkg CI builds for SECURE_BOOT_ENABLE=TRUE
for IA32/X64 and DEBUG/RELEASE/NOOPT.  Label these as
FULL builds, so if additional build options are added
in the future, they can be added to these FULL builds.
