Finish CONFIG_VID et al conversion to Kconfig

This converts the following to Kconfig:
   CONFIG_VID
   CONFIG_VOL_MONITOR_INA220
   CONFIG_VOL_MONITOR_IR36021_READ
   CONFIG_VOL_MONITOR_IR36021_SET
   CONFIG_VOL_MONITOR_LTC3882_READ
   CONFIG_VOL_MONITOR_LTC3882_SET

To finish this migration, we first need to introduce CONFIG_SPL_VID as
some platforms only use this code in full U-Boot while others use it in
SPL as well.  To make the Kconfig logic clearer, guard all of the
sub-options with a if VID || SPL_VID check.  Finally, add Kconfig
options for the remaining related options that did not previously have
one.
