The Simple Boot feature for Espressif chips is a method of booting
that doesn't depend on a 2nd stage bootloader. Its not the
intention to replace a 2nd stage bootloader such as MCUboot and
ESP-IDF bootloader, but to have a minimal and straight-forward way
of booting, and also simplify the building.
This commit also removes deprecated code and makes this bootloader
configuration as default for esp32 targets and removes the need
for running 'make bootloader' command for it.

These configs are changed based on below rules.
1. always enable +CONFIG_LV_USE_NUTTX=y
2. If touchpad is used, enable +CONFIG_LV_USE_NUTTX_TOUCHSCREEN=y
3. enable log by +CONFIG_LV_USE_LOG=y
4. If -CONFIG_LV_MEM_CUSTOM=y previously defined, replace it with +CONFIG_LV_USE_CLIB_MALLOC=y +CONFIG_LV_USE_CLIB_SPRINTF=y +CONFIG_LV_USE_CLIB_STRING=y
5. If -CONFIG_LV_PORT_USE_FBDEV=y, default config is for fbdev. If -CONFIG_LV_PORT_USE_LCDDEV=y, +CONFIG_LV_USE_NUTTX_LCD=y
6. Remove all -CONFIG_LV_TICK_CUSTOM=y -CONFIG_LV_TICK_CUSTOM_INCLUDE="port/lv_port_tick.h"
7. If -CONFIG_LV_PORT_LCDDEV_DOUBLE_BUFFER=y, replace it with CONFIG_LV_NUTTX_LCD_DOUBLE_BUFFER=y. For fbdev, double buffer is automatically detected.
8. If -CONFIG_LV_COLOR_16_SWAP=y, need to upgrade the LCD driver to support hardware byte order swap.

This commit provides an interface to register ISRs that run from
IRAM and keeps track of the non-IRAM interrupts. It enables, for
instance, to avoid disabling all the interrupts during a SPI flash
operation: IRAM-enabled ISRs are, then, able to run during these
operations.
It also makes the code look more similar to the ESP32-S3 SPI flash
implementation by creating a common `esp32_spiflash_init` that is
responsible to create the SPI flash operation tasks. The function
intended to initialize the SPI flash partions was, then, renamed to
`board_spiflash_init`.
In order to better test the lcdddev driver and framebuffer, newer
board configs (for the TTGO T-Display and for the simulator) were
added.
Adjusted references of the sim:lvgl_(fb/lcd) config.
