[RichTextBlock][Android] Update existing richtextblock implementation to match new specification for 1.2

[shalinijoshi19]

To address the length concerns, we’re simplifying the payload
a. Removing the concept of paragraphs, so it’s just a set of inlines
b. Syntax sugar for auto-converting a text string into a basic TextRun
For the wrap/maxLines
a. Remove those properties
For the markdown inside runs
a. Don’t support markdown
For being able to use italics within runs (since no markdown)
a. Possibly add an “italicize” property to TextRun
Changes…

Removed “paragraphs”. Now it directly goes to “inlines”
Syntax sugar for converting a text string into a basic TextRun object (to reduce payload size when you don’t need any special formatting)
Removed “wrap” and “maxLines” properties
Removed markdown support from TextRun
Added “italicize” (name pending) to TextRun so you can italicize text
