[tracing] Sanitize process memory dump names for background mode
For background mode:
1. ProcessMemoryDump knows the level of detail.
2. It checks for dump name to be present in whitelist. If not then
returns a dummy mad. The strings are stripped of numbers (ids) and
checked against a whitelist of dump names.
3. Disable creating new dumps just to mark suballocations.
4. Disable creation of global allocator dumps.
5. Disable string attributes in allocator dumps.
Also creates a new whitelist file to handle whitelisting logic.
