[scudo] Add static vector functionality. (#98986)
The scudo vector implementation maintains static local data before 
switching to dynamically allocated data as the array size grows.
Users of the vector must now specify the size of the static local data 
through the vector template (the default size has been removed). 
If 0 is specified for the size of the static local data, an assertion
will
be triggered.
