refactor(spi): moved spi hw sharing func to hw support

Browse Source 
Common spi functionality for sharing the SPI bus between modules is moved from esp_driver_spi to
a more fitting location in esp_hw_support (shared HW resource control).

This also allows us to decouple the spi_flash driver from esp_driver_spi, removing
esp_driver_spi and esp_ringbuf from G1 builds.
