Add mcfunction profiler support

[MATRIX-feather]

Description

Currently, Spark doesn't seem to have mcfunction support, if some function consumes too much time, the profiler result would only show CustomFunctionCallbackTimerQueue or something else related to the function execution instead of a specific function name:

Proposed Behaviour

mcfunctions would appear in the profiler result in line with other methods, or another view like PluginsView for Spigot servers
