Set of refactors for Kernel Synchronization and Hardware Constants

shader/decode: Fix constant buffer offsets

Use config mode for finding SDL2 with CMake

Available as a drop down within the configure graphics tab.

update hwopus DecodeInterleaved for FW 7.0.0+

GPU: Refactor queries implementation and correct GPU Clock.

address_arbiter: Minor cleanup to list querying

Same behavior, but without the need to explicitly loop through

const-qualified member function.

bcat/backend: Prevent fmt exception in debug log within NullBackend::Clear()

kernel/thread: Remove trivial usages of the global system accessor

Aligns the '=' to be consistent with the rest of the logs within this
source file.

A formatting specifier within Clear wasn't being used, which will cause
fmt to throw an exception. This fixes that.

We can just use the kernel member variable directly instead of going
through the system to obtain the same thing.
