roll: third_party/pigweed pw_tokenizer: Apply no_sanitize("address") to tokenizer string entries
ASAN applies a 32-byte alignment to global variables as part of its
redzone strategy. This breaks the requirement that the
_pw_tokenizer_string_entry_* variables are 1-byte aligned so they appear
consecutively in the ELF section without any padding.
This isn't normally an issue as ASAN isn't used on firmware builds where
tokenization is used. But in the case of self-detokenizing programs
(namely tests), this causes ASAN violations and corrupt token entry ELF
section data.
Applying __attribute__((no_sanitize("address"))) to these variables
bypasses this behavior.
