BLE 33 - .overlay updates, enable Wire1, pins match MBED, change analogRead to 12 bit

Resolves: #49 #48

Note: @mjs513 has a version of the wire scanner that works with this.
however Wire object takes a while to scan unless external PU resistors are connected to SCL/SDA pins.
The sketch also turns on the Wire1 PU resistors and enables the Wire1 objects, using D32 and D33 below.
These pins are shown on the schematics for the different versions of the Nano 33 BLE boards.

Also @mjs513 found an interesting web page:
https://github.com/saltyJeff/zephyr_arduino_nano_33_ble/blob/main/src/init_arduino_style.c
Which also confirmed the need to initialize the two pins on Wire1 for the devices to work.

Extra pins:

 					<&gpio0 24 0>,	/* D22 LED R */
  					<&gpio0 16 0>,	/* D23 LED G */
  					<&gpio0 6 0>,	/* D24 LED B */
  					<&gpio1 9 0>,	/* D25 LED PWR */
  					<&gpio0 19 0>,	/* D26 INT APDS */
  					<&gpio0 17 0>,	/* D27 PDM PWR */
  					<&gpio0 26 0>,	/* D28 PDM CLK */
  					<&gpio0 25 0>,	/* D29 PDM DIN */
  					<&gpio0 14 0>,	/* D30 SDA2 */
  					<&gpio0 15 0>,	/* D31 SCL2 */
  					<&gpio1 0 0>,	/* D32 I2C_PULL */
  					<&gpio0 22 0>;	/* D33 VDD_ENV_ENABLE */

Note some of these pins are important to enable Wire1 to work. Including enabling power to the sensors as well as to enable the Pull up resistors on the Wire1 object.

Added Wire1 object to the list of wire bojects.
Set default clock-frequency on the two I2C objects, like the GIGA has defined.

Also changed the ADC conversion resolution for all of the channels from 10 bits to 12, as that is I believe the maximum the device supports. So when we pull in the PR for analogRead it should then map down to the resolution the user chooses with analogReadResolution call.

Between @KurtE and myself we tested on
Nano 33 sense BLE V1
Nano 33 sense BLE V2
and
Nano 33 BLE.

Only remaining issue is that setting a clock to 100Khz/I2C_SPEED_STANDARD remains flaky - see issue for more details

@facchinm - I added the turn on FPU in this PR as well.
Fixed a lot of weird crashes!

@KurtE I refactored your commits a bit to have only one loader rebuild and pushed zephyrproject-rtos/zephyr#84675 to our fork while waiting for upstream to apply it ( see https://github.com/arduino/zephyr/tree/arduino_core_merge_4.0.99 ).
After the CI completes, we should have all the needed fixes applied for nano33ble
