SPI devices are now configured using static array in header files instead of static variables in implementation to be able to define SPI_NUMOF using the size of the array instead of a variable.

Contribution description
This PR changes the approach of peripheral configurations for SPI interfaces in board definitions to the usual RIOT approach. With these changes, peripheral configurations use static const arrays in the
boards/esp32*/periph_conf.hfiles and define the*_NUMOFmacros using the size of these static array.The static configuration arrays contain only definitions that can be changed by the board definition or the application. They do not contain any MCU implementation detail. The board definitions use preprocessor defines as before to fill these static configuration arrays. This makes it possible to override all configurations either with the make command or application specific configuration files.
Please note that commit 8b48dfd is in also in related PRs to get each PR compilable separately.
Testing procedure
Compilation and test with the most common ESP32 board should be executed
