[esp32] update MICROLITE board config for latest micropython
I copied the micropython board ESP32_GENERIC and replaced MICROLITE with minor adjustments to enable the microlite module and the name of the board.

The following files are firmware that should work on most ESP32-based boards
2+
with 4MiB of flash, including WROOM WROVER, SOLO, PICO, and MINI modules.
3+
4+
If your board is based on a WROVER module, or otherwise has SPIRAM (also known
5+
as PSRAM), then use the "spiram" variant.
6+
7+
The "d2wd" variant is for ESP32-D2WD chips (with 2MiB flash), and "unicore" is
8+
for single-core ESP32 chips (e.g. the "SOLO" modules). The "ota" variant sets
9+
up the partition table to allow for Over-the-Air updates.
