The backend rasterizes coverage (or color, for emoji) as usual, then a
shared CPU pass pads the bitmap, blurs an offset copy of the coverage
and composites the text over it as RGBA8888. Blur and offset scale with
the font size and with DPI. The flag is part of the string cache key,
and the text is still aligned by its own size, with the quad grown to
fit the shadow.

These own GPU objects, memory or refcounts in their destructors (or assert
there that they were torn down), so a copy would double-free. Nothing copies
them today; this keeps it that way. The manager base classes cover every
backend's subclass.

The only guard against writing past the fixed 65536-entry verts_
array was _dbg_assert_msg_, which is compiled out entirely outside
_DEBUG - a large enough single batch (e.g. Circle()/CircleSegment()
with a big segment count, or a large UI list without an intervening
Flush()) silently corrupted the heap in release builds. Added a real
bounds check that drops the vertex instead.

The adreno test tests for the bug mentioned in #13910.
Very clear repro on Adreno 630, Pocophone F1.
The flat shading test is an untested attempt at a repro of
(will test that tomomorrow).
