Add support for Draco (.drc) format (#10681)

Browse Source 
* Add read support for Google's Draco (.drc) format.

* Fix build on Linux

* Use boost instead of fstat.

* Switch to boost memory-mapped file to save RAM and potentially improve performance.

* Trim trailing whitespace.

* Initial Draco write support.

Currently always exports with 16-bit precision and speed 0 (best compression).
The back-end function does have arguments to specify them, it's just not hooked into the GUI.

* Add Draco to the About dialogue.

* Fix Linux compile (hopefully)

* Add an option to associate DRC files on Windows.

* Implement a Preferences option to set Draco position quantization bits

* Update src/slic3r/GUI/Preferences.cpp

* Some slight changes to ianalexis's suggestion.

* Implement a create_item_spinctrl() function for numeric inputs, and use that instead of create_item_input().

* Move "bits" to inside the spinctrl box.

* Refactor following yw4z's feedback

* Update src/slic3r/GUI/Preferences.cpp

Co-authored-by: Ian Bassi <ian.bassi@outlook.com>

* Change to 0 bits as the default setting for Draco export precision.

* Change to a lossy checkbox and a bits field with a range of 8-30.

* Proper SpinInput code from yw4z

* Revert "Proper SpinInput code from yw4z"

This reverts commit 7e9c85f31a.

* Revert "Change to a lossy checkbox and a bits field with a range of 8-30."

This reverts commit d642c9bcc0.

* Redo preferences based on SoftFever's feedback

* Refactor to minimize code duplication

* Fix padding

* Improve Draco export quality level tooltip clarity

Clarify that 0 means lossless compression (not uncompressed),
document the valid lossy range (8-30), and better explain the
tradeoff between file size and geometric detail.
