Fix #116243, #122022 - metalrt live viewport stability issues

This PR fixes live viewport stability issues on Mac when MetalRT is enabled.

There were two sources of instability:

1) `MTLAccelerationStructure` instances were not being correctly retained meaning that use-after-free crashes could occur following a geometry sync.
2) `MTLIntersectionFunctionTable` objects could be unsafely shared between multiple `MetalDeviceQueue` instances (in this case, `setBuffer` being the unsafe mutation)

The solution to 2 involves creating a new `MetalDispatchPipeline` type which is strictly used by only 1 `MetalDeviceQueue` instance.

Bump libraries version

Oneapi: avoid crashes from old drivers

During recent testing, the oldest 101.4032 (windows) and <25812 (linux)
drivers led to crashes during JIT compilation, so we bump the
requirement to newer 101.4313 and 25812.14 drivers that do incorporate
the required fixes.
