This driver is based on ESP32 TWAI CAN drivers currently available
in Nuttx, and captures the differences currently present across the
TWAI drivers for easy future adaption to remaining ESP32 platforms
with no loss of support/function. Also provides a generic SJA1000 CAN
driver solution that is CPU-architecture independent.
Changes:
- Low-level driver re-written to allow usage independent of CPU
architecture, and support both SJA1000 and TWAI CAN controllers.
- Platform-specific settings abstracted away to be provided by board
layer.
- Support for multiple instances of SJA1000 driver.
In the past, header file paths were generated by the incdir command
Now they are generated by concatenating environment variables
In this way, when executing makefile, no shell command will be executed,
it will improve the speed of executing makfile

This reverts commit b9ace36fcc.
This change was added by PR 625 but has a serious logic flaw. It removes all occurrences of INCDIROPT and replaces it with a definition in tools/Config.mk:
else ifeq ($(WINTOOL),y)
DEFINE = "$(TOPDIR)/tools/define.sh"
INCDIR = "$(TOPDIR)/tools/incdir.sh" -w
This logic flaw is the Config.mk is included in all Make.defs files BEFORE WINTOOL is defined. As a result, the definition is wrong in many places when building under Cygwin with a Windows native toolchain.
