examples: keep CFG_TUH_VENDOR 0 in tusb_config.h

Removing the obsolete host vendor driver also dropped the `#define CFG_TUH_VENDOR 0`
line from the six example configs that carried it. Put it back: host vendor is
coming, and the configs are where a reader looks for the set of host classes an
example can turn on.

Restored byte-identical to the pre-removal state, each file keeping its own column
alignment. The define is inert today - nothing under src/, hw/ or tools/ reads
CFG_TUH_VENDOR - and it is 0 everywhere, so ci_select still reads the vendor class
as enabled by no example and a change to it still selects nothing.

Note the option's default in src/tusb_option.h is still gone; implementing the
driver will need that back alongside the usbh driver-table entry.
