Fix GH-41226

[knappam]

When not drawing a border, the mGapBetweenPaths adjustment can create noticeable pixelation when drawing curves through a low number of pixels. This is noticeable mostly on buttons and such on low-dpi devices. This fix only applies the fix if clipping for the border radius is done.

Summary:

When drawing small radius rounded backgrounds (e.g. to draw a circle or button) we see visible pixelation. This is particularly noticable on low DPI devices.

Changelog:

[ANDROID] [FIXED] - Don't use mGapBetweenPaths if not drawing a border

Test Plan:

Built an android app that directly uses ReactViewBackgroundDrawable to draw a background and verified repro of this issue.

Then modified the code according to this PR and verified that anti-aliasing is appropriately applied
