seems like hspi and vspi are two separate groups of SPI peripherals offered by the esp32 board.

i cannot come up with a possible explanation for the expansion of these acronyms. Someone suggested "Hardware and Virtual", which could be close. :)

There is no meaning that we (=any colleague engineer within Espressif I asked) know of; if the original designer did have one in mind it's lost to time.
