Currently, the sanitizers are suppressed based on the contents of files in the etc/ directory. Those filenames are currently suffixed with .blacklist . We should replace those suffixes with denylist so that the new filenames follow the pattern etc/.denylist.
Additionally, numerous variable names and comments in SConstruct reference the terms "blacklist" and "blackfile". These should be replaced with "denylist" and "denyfile", respectively.
Note that references to - fsanitize-blacklist should NOT be changed by this ticket as they are dependent on upstream work that is not yet available in our toolchains.
