Enabling misc-misleading-identifier and misc-homoglyph in clang-tidy

[Ryan Beltran]

Hi all,

I'm planning on enabling misc-misleading-identifier and misc-homoglyph in chromium's clang-tidy profile. Together, these should help defend against various forms of Trojan Source attacks. I tested these lints for Chromium Browser and, unsurprisingly, there were zero occurrences which tells me that the noise from this should be very low.

LLVM blog post describing these lints: https://blog.llvm.org/posts/2022-01-12-trojan-source/

Does anyone have any concerns on moving forward with this?
