Add purity annotations to newly added functions

[SupunS]

Issue to be solved

There are some native function types added to the master branch, after the purity annotation change was added in stable-cadence. e.g:

• Address.fromBytes()

When the stable-cadence branch is synced/merged to master, ensure these newly added functions have the proper purity annotation.

Suggested Solution

Scan through all the newly added functions, and added annotations as required.

I ran go run ./runtime/cmd/info -nested -members dump-builtin-types and go run ./runtime/cmd/info -nested -members dump-builtin-values and fixed and other then some missing view annotations for functions related to InclusiveRange I could not see any other issues.

Improved the functions related to InclusiveRange in #3426
