[Physics] Using huge numbers of vertex for Polygon/Edge collider causes stack overflow.

Physics2D

-

Steps to repro:
1. Open attached project
2. Hierarchy > 2D Object > Sprite
3. Inspector > Add component > Polygon Collider 2D
4. Inspector > Polygon Collider 2D > Points > Paths > Size
5. Enter a high value more than 10000 for 'Size'

Actual Result:
Editor crashes on entering values much more than 10,000.

Expected Result:
Editor may freeze whilst it processes large numbers of vertex (etc) but it should not crash.

Note:
The attached video shows 20 million paths being added which produces 20 million 5 vertex shapes so 10 million shapes. The Editor will stop responding (freeze) because it's doing a lot of work and will likely take many hours and possibly days to process that.

Reproducible in:
2020.1.0a19, 2019.3.0f6, 2018.4.13f1, 2017.4.34f1, 2017.1.5f1
