Sudeep Mohanty 26c19928a9 feat(freertos): Place FreeRTOS in flash by default 
The following updates have been made in this commit:
- The commit places FreeRTOS code in flash memory by default.
- CONFIG_FREERTOS_PLACE_FUNCTIONS_INTO_FLASH has been removed.
- CONFIG_FREERTOS_IN_IRAM is unhidden and can be used to restore the
  previous memory placement.
- A test has been added for users to conduct performance impact testing
  based on memory placement configurations.

Michael (XIAO Xufeng) 8cddfa35b8 spi: fix the crash when callbacks are not in the IRAM 
Introduced in 9c23b8e5 and 4f87a62f. To get higher speed, menuconfig
options are added to put ISR and other functions into the IRAM.  The
interrupt flag ESP_INTR_FLAG_IRAM is also mistakenly set when the ISR is
put into the IRAM. However callbacks, which are wrote by the user, are
called in the master and slave ISR. The user may not be aware of that
these callbacks are not disabled during flash operations. Any cache miss
during flash operation will cause panic.

Essentially IRAM functions and intrrupt flag ESP_INTR_FLAG_IRAM are
different, the latter means not disabling the ISR during flash
operations.  New bus_config flag intr_flags is offered to help set the
interrupt attribute, including priority level, SHARED, IRAM (not
disabled during flash operations).  It introduced a small BREAK to
IDFv3.1 (but the same as IDFv3.0) that the user has to manually set IRAM
flag now (therefore he's aware of the IRAM thing) to void the ISR being
disabled during flash operations.
