Add ability to reserve psram 

.. the primary user of which will be the camera, since the framebuffers
must be allocated via esp-idf allocation function and never from the
gc heap.

A board can have a default value, and the value can also be set in the
/.env file using the key CIRCUITPY_RESERVED_PSRAM with the value being
the reserved size in bytes.

@ -35,6 +35,12 @@ CIRCUITPY_BLE_NAME
~~~~~~~~~~~~~~~~~~
Default BLE name the board advertises as, including for the BLE workflow.
CIRCUITPY_RESERVED_PSRAM
~~~~~~~~~~~~~~~~~~~~~~~~
On boards with Espressif microcontrollers with PSRAM (also called SPIRAM), permanently reserve a portion of PSRAM for use by esp-idf.
This storage is removed from the CircuitPython "heap" and is available for allocation by esp-idf routines in the core instead.
Generally, only set this to a non-zero value when it is required by a specific core module.
CIRCUITPY_WEB_API_PASSWORD
~~~~~~~~~~~~~~~~~~~~~~~~~~
Password required to make modifications to the board from the Web Workflow.
