Bluetooth (#518)

* Bluetooth LE addition

* fixes

* use the psram!

helps a little on S3 (t-deck)

* custom device name

* Update symbols.c

* Feedback + fixes

Fixes external app start/stop server (child devices)
Fixes BtManage causing a full system hang upon disabling bt when a device is connected to the host.

* updoot

* more updoot

* move back!

* Revert "move back!"

This reverts commit d3694365c634acc5db62ac59771c496cb971a727.

* fix some of the things

* Addressing feedback? hmm

* Fixes

Bug 1 — Reconnect loop / Reconnect not working fixed
Bug 2 — Name-only advertising overwrites HID advertising
Bug 3 — BleHidDeviceCtx leak on re-enable
Enhancement — HID device auto-start on radio re-enable

* stuff...

* update for consistency with others

* fix crashes

and some bonus symbols

* a few symbols, i2c speed, cdn message

100kHz i2c speed seems to be more compatible with m5stack modules...and probably in general.
cdn message no longer applies

* Hide BT Settings when bt not enabled

* Addressing things and device fixes

* Missed one!

* stuff
