Fix -Wreturn-type in ShadowSamplerFunctionsTest::FunctionName
Add UNREACHABLE() and a fallback return to ensure the non-void function
always returns when switch does not cover all enum values.

Metal: Rework allowSamplerCompareGradient feature
* AMD drivers may fail when a sample_compare function is
used with explicit derivatives. To avoid such failures,
the effective level is computed from the texture size,
passed derivatives, and texture coordinates, if needed.
The level value is then used for sample_compare instead
of the explicit derivatives.
* Apple2 GPUs do not support setting texture sampler compare state
via Metal API. As a result, all sample_compare functions including
those without LOD options do not work on Apple2 GPUs. This feature
was attempting to incorrectly emulate a subset of sample_compare
functions with a hard-coded compare state.
There are no plans to support shadow samplers on Apple2 GPUs,
as it would require non-trivial emulation, so this feature is
no longer relevant for that platform.
* Metal on macOS 10.15 only supports constant zero as
the level parameter for sample_compare functions.
Ignoring the passed derivatives and using zero LOD on old OS
versions is a better fallback than dropping the derivatives
altogether because many applications use the derivatives to
set the level to zero anyway.
