* feat(wifi): add compile time configurtation
Add `WLED_AP_SSID` and `WLED_AP_PASS` defines to allow configuring the
SoftAP SSID and Password at compile time. Default to existing values.
Add `WLED_AP_SSID_UNIQUE` flag to append the device portion of the mac
address to `WLED_AP_SSID`.
Exampleof all flags (note the quoting to preserve
"stringification"):
```
build_flags =
-D WLED_AP_SSID='"MyAP"'
-D WLED_AP_PASS='"MyPassword"'
-D WLED_AP_SSID_UNIQUE
```
* Removed two error defines

- added "max used PSRAM" info
- moved all mem infos into one part
- only check PSRAM if BOARD_HAS_PSRAM
- oappend: debug message in case that stack buffer is too small.
This is a nice little chip info tool that I've created some time ago.
When building with `-D WLED_DEBUG`, it reports some interesting information about your ESP32 on serial monitor.

This fixes a "division by zero" in WLED_DEBUG code.
LittleFS init seems to take some time, so we can arrive at "Loops/sec" with 0 loops executed --> crash.
- adding USB-OTG to reserved GPIO
- no read-only GPI
- if PSRAM found, add pins for "octal" PSRAM to unusable list (octal PSRAM seems to common on S3)
- ESP32: 37 and 38 are read-only
handleImprovPacket() unconditionally gobbles serial data which a problem
if we want another feature to consume it. This patch uses the same guard
as the existing call in `handleSerial()`.
