Clear needs context

[timse201]

Right now, we have 2 strings for clear. One with context verb and one without. A better way would be to separate them with the context clear/reset that value and clear that field.
I did not dig into every string but it would be helpful.

This pull request updates the translation functions for the "Clear" button in several places to provide more context for translators. By switching to the contextual translation function (_x or esc_html_x) and supplying a descriptive context string, the changes help ensure accurate and meaningful translations in different scenarios.
