drivers/intel/fsp2_0: introduce possibility of using a full FD binary

Currently, setting a custom FSP binary is only possible by using split
FSP-T/M/S FD files. This change introduces the possibility to pass a
combined FD file (the "standard" FSP format).

This is done by adding a new boolean Kconfig FSP_FULL_FD, specifying
that the FSP is a single FD file instead of split FSP-T/M/S FD files,
and making FSP_FD_PATH user-visible when the option is chosen. In this
case, the other options for split files get hidden.

When the user chooses to use a full FD file instead of the split ones,
the FD file gets split during build, just like it is done when selecting
the Github FSP repo (FSP_USE_REPO).

Test: Supermicro X11SSM-F builds and boots fine with custom FSP FD set.
