Added logic to only override role description that is said on TalkBack if it's in english.

Summary:
Context:
On Android, I am currently overriding the role description for TalkBack on certain Roles. Currently, these are done only in English.
I needed to add a checker that only overrides these role descriptions if the language of the phone is set

Changes:
* Added a language checker before I call setRoleDescription
* Put the strings into variables.

Note:
This is done to prioritize a codemod for accessibilityRole. Eventually, we hope to add support for other languages on these roles.
