tools: k3_gen_x509_cert: Allow selecting early JTAG debug value
When authenticating the initial boot binary the ROM will check a debug
type value in the certificate and based on that open JTAG access to that
core.
Make this selectable in the signing tool to allow it to be enabled or
disabled based on user command line input.
This does not change the default behavior.
