InputControl/TextControl: Force direction to LTR for certain fields

What problem does this address?

For example, in the email and url fields, the text direction is usually expected to be ltr.

There is a style in WordPress core that will change the direction to ltr:

However, this style does not necessarily apply to the block editor.

For example, in the Embed block that uses the InputControl with a url type, the direction is RTL, as shown below:

What is your proposed solution?

As with core, if the type attribute is url or email, I suggest adding direction: ltr.

However, there seem to be various approaches to making form fields RTL-compatible. Please refer to the following article:
