Various Benchmark Fixes for AzCore (#7611)

Browse Source 
Fixed crash in Allocators Benchmark multithreaded test due to the HPHA schema not having proper multithread protection around the `mFreeTree` member in `tree_get_unused_memory` function.
The `mFreeTree intrusive set is able to modified on multiple threads.

Replaced the custom intrusive_list implementation n HPHA schema with AZStd::intrusive_list

Added a `ScopedAllocatorBenchmarkEnvironment` class to provide an RAI mechanism for initializing the SystemAllocator in Benchmark Test

Rermoved the `AzCoreBenchmarkEnvironment` in lieu of the `ScopedAllocatorBenchmarkEnvironment` class

Fixed assert when running Allocator Benchmarks in debug due to mismatch PauseTiming/ResumeTiming in Allocator Benchmark Fixtures

Added `ScopedRegisterBenchmarkEnvironment` RAII class to provide lifetime guarantees on BenchmarkEnvironments registered via the `AZ_UNIT_TEST_HOOK`

Initialized the intrusive_multiset_node members to nullptr in all build configurations instead of only debug as the cost negligible and it is useful for debugging.
