fix(std/encoding/toml): Stop TOML parser from detecting numbers in strings. (#7064)

Before this patch the TOML parser would incorrect treat the string
"base64data0xdamaged" in a declaration as a hex number because the
corresponding check triggers even when the "0x" is inside a double
quoted string literal as long as it is followed by at least one hex
character.
