[URP] Particles have green and pink artifacts when used with Transparent Shaders
How to reproduce:
1. Open the attached "1240033 repro" project
2. Open the "SampleScene" from Assets > Scenes folder
3. Enter Play Mode and wait a little bit for all of the particles to spawn
4. Switch from Game view to Scene view without exiting Play Mode
Expected result: the particle cloud doesn't have any pink or green artifacts in the 3rd step just like in the 4th step
Actual result: the particle could has pink and green artifacts after the 3rd step
Reproducible with: 7.0.0 (2020.1.0a19), 7.0.1 (2019.3.0b1), 7.2.1 (2019.3.13f1), 7.1.8 (2019.3.7f1), 7.3.1 (2019.3.13f1), 8.0.1 (2020.1.0b8), 8.1.0 (2020.1.0b8), 9.0.0-preview.14 (2020.2.0a10)
Not reproducible with: 2.0.8-preview (2018.4.23f1), 3.3.0-preview (2018.4.23f1), 4.10.0-preview (2018.4.23f1), 5.16.1 (2019.3.0a1), 6.7.1 2019.3.0a1, 6.9.2 (2019.2.21f1)
Could not test with: 1.1.11-preview and earlier (project errors)
Notes:
-This reproduces with Direct3D12, Direct3D11, OpenGLCore, OpenGLES2, OpenGLES3, Vulkan and Metal
-The artifacts can be clearly or barely visible depending on the background and view angle
-This reproduces with Unlit/Transparent, URP/Lit, URP/Unlit Shaders
-The "Transparent" option must be selected on URP/Lit and URP/Unlit Shaders in order to reproduce this issue
-Color Mode of the Shader can alter the way artifacts look but none of the modes removes them completely
-The artifacts are usually located around the edges of the particle cloud but sometimes in cross-sections of the cloud too

Resolution Note:
RG11B10f has different precision for channels which can introduce colored banding in some cases. A color buffer format option should be added to URP pipeline asset just like in HDRP.
