Fixes #19028

### Summary of the issue:

Papenmeier braille displays don't work with 64-bit NVDA.

### Description of user facing changes:

Papenmeier displays should work again.

### Description of developer facing changes:

* `ftdi2.py` has been moved from `miscDeps` into `nvda`, and
significantly refactored.

### Description of development approach:

* [x] Copy `ftdi2.py` from `miscdeps/python` to
`source/ftdi2/__init__.py`
* [x] Reimplement `ftExceptionDecorator` as a ctypes `errcheck` function
* [x] For each of the `_PY_*` functions, look up the corresponding
function in the [D2XX Programmer’s
Guide](https://ftdichip.com/document/programming-guides/) (revision 1.6)
and implement the corresponding ctypes prototype in `ftd2xx.py`
* [x] Convert enumerations to actual `Enum`s, and move to `ftd2xx.py`
* [x] Verify struct definitions
* [x] Rename the various pythonic functions and methods according to NV
Access' house style
* [x] Update the copyright headers and docstrings
* [x] Compare the old `ftdi2.py` wth the new `ftdi2` package and
document API differences
* [x] Remove `ftdi2.py` from miscdeps (PR nvaccess/nvda-misc-deps#46)
* [x] Update miscdeps

### Testing strategy:

Asked affected users to test try builds.

### Known issues with pull request:
