New dice-rolling app: InfiniDice! (#1326)

Add new App `Dice.h` to randomly roll the dice(s).
The number of dice can range from 1-9 (default 1), and the sides can
range from d2-d99 (default d2).

To have a haptic feedback we make Dice vibrate on roll.

Regarding the use of C++ `<random>` library:
There are known problems with `rand()` and `srand()` (see https://en.cppreference.com/w/cpp/numeric/random/rand)
and the `<random>` library is preferred for this reason. The function used from
`<random>` also avoids a very rare bias that would occur using `rand()` and modulo,
when `RAND_MAX` is not a multiple of `d` and the initially generated number falls in
the last "short" segment. This commit also updates the seed to derive entropy
(via `seed_seq`) from a mix of the system tick count and the x,y,z components of the
PineTime motion controller -- taking inspiration from and with credit to @w4tsn
(https://github.com/InfiniTimeOrg/InfiniTime/pull/1199)

Thanks for suggestions:
* in Dice, when rolling 1d2, also show "HEADS" or "TAILS" -- suggestion by @medeyko
* ui adjustments and result realignment -- suggestion by @Boteium
