Proposal: a11y eslint rules

[splincode]

@taiga-family/core-team should we enable some A11 accessibility presets?

1. role-has-required-aria

2. valid-aria

3. label-has-associated-control

4. click-events-have-key-events

5. elements-content

6. mouse-events-have-key-events

Which of them would be useful?

1 — we can try it, let's see what we are missing
2 — sounds good, it is mostly just checking for typos if I understood it correctly.
5 — we can probably enable, it's good practice to have text inside tuiIconButton for a11y, that's why we set font-size: 0 there.

3, 4 and 6 I'm skeptical about

Okey, I will try to add 1, 2, 5 rules
