Fix Allure Mocha ESM parallel; add deprecation warnings to the legacy API

[delatrie]

Context

Some fixes for Allure Mocha:

• Fix the ESM version in parallel mode: now import.meta is used instead of __dirname. The babel-plugin-transform-import-meta plugin is used to transpile that construct to CommonJS.
• deprecation warnings were added to the legacy API
• MochaAllureReporter was renamed to AllureMochaReporter
• runtime.ts was removed (it's not in use now)

Test improvements for Allure Mocha:

• switching between esm and cjs samples (controlled by ALLURE_MOCHA_TEST_SPEC_FORMAT, the default is esm).
• switching between the CLI and code runners, where the code runner can be in the esm or cjs format (controlled by ALLURE_MOCHA_TEST_RUNNER, the default is cli).

Linting fixes:

• dist folders were removed from ESLint globally
• no-require rules were disabled for Allure Mocha CommonJS files
