MI32 legacy: add config operations for Berry

[Staars]

Description:

Add a few BLE operations to configure some options of the BLE stack at runtime when acting as a central device. These are executed immediately.
This can be helpful to emulate other devices like AirTags for educational purposes or explore projects like openhaystack.

Op code | function:
231 - set own address to random:

        var m = bytes(aabbccddeeff).reverse() # directly set value of ble_addr_t, which is reversed
        BLE.set_MAC(m,1) # 1 -> address type random
        BLE.run(231)

232 - set advertising parameters with bytes()-descriptor of length 5 [advType:byte, minInterval:uint16_t, max interval: uint16_t]

   #BLE_GAP_CONN_MODE_NON    (0) - not connectable advertising
   #BLE_GAP_CONN_MODE_DIR    (1) - directed connectable advertising
   #BLE_GAP_CONN_MODE_UND    (2) - undirected connectable advertising

    var minitvl = int(1000 / 0.625) # in 0.625ms units
    var maxitvl = int(2000 / 0.625) # in 0.625ms units
    cbuf.setbytes(0,bytes("050200000000")) # 5 bytes, type 2 
    cbuf.seti(2,minitvl,2)
    cbuf.seti(4,maxitvl,2)
    BLE.run(232)

233 - set GAP name of the device

var name = "Tasmota BLE“
    cbuf[0] = size(name) + 1
    cbuf.setbytes(1,bytes().fromstring(name))
    BLE.run(233)

A partial backport of esp-nimble-cpp is included, but there are many other breaking changes upstream. Thus we will not update the whole library for now.
