peripheral enable/disable usually should be managed by driver itself,
so make it as espressif private APIs, not recommended for user to use it
in application code.
However, if user want to re-write the driver or ports to other platform,
this is still possible by including the header in this way:
"esp_private/peripheral_ctrl.h"
When `DIS_USB_JTAG` eFuse is NOT burned (`False`), it is not possible
to set pins 18 and 19 as GPIOs. This commit solves this by manually
disabling USB JTAG when using pins 18 or 19.
The functions shall use `gpio_hal_iomux_func_sel` instead of
`PIN_FUNC_SELELECT`.
