malloc: Add a Kconfig option for heap protection

Browse Source 
Add CONFIG_MCHECK_HEAP_PROTECTION option to enable mcheck heap
protection. Convert all uses of MCHECK_HEAP_PROTECTION to use the
CONFIG_ -prefixed version to work with Kconfig.

Disable this option when tracing is enabled, since the mcheck hooks (mcheck_pedantic_prehook(), etc.) interfere with function tracing.
