[Post Excerpts]: Add support to show font styling used in the post's content

[joweber123]

Steps to reproduce

1. Add any font style (Bold, Italics, Underline, etc) to a post.
2. Add the Blog Posts block to a page.

What I expected

I expected that font styles would be displayed in the excerpt of the posts in the Blog Posts block

What happened instead

Styles are stripped from the excerpt of the post.

Had a user request this in 36159671-hc.

I confirmed on a test site that this affects the Blog Posts block, Latest Posts block, and the Query Loop block.
