API: Move and rename purchased server functions to cloud API (#2367)

* Convert purchased server functions to cloud API

- Create `ns.cloud`
- Change `bitnode multipliers` and `server constants` wording for consistency
- change `server`, `ram` and `getting started` docs for consistency
- Added changes to 3.0.0 API Break and `setRemovedFunctions` in NetscriptFunctions.js

Tested by
- running tutorial `purchase-server-8gb.js`, and a more typical player one
- buying manually using vendor (Alpha Ent in Sector 12)
- deleting them all using script, and checked all deleted functions gave correct error
- Imported completed save to ensure auto-transfer of function work

* Revision in line with comments

- changed more `purchased` to `cloud` references
- Added BN mults auto-conversion

* Update getting_started.md

 - Corrected function names for new `cloud API`

* Don't show `cloud API` warning

v3.0.0 API break auto-replaces `cloud` functions, not warning suggested.

* API Break correction

- `cloud` affected API break replacement changed to be more descriptive and functional

* Fix typo and add empty lines

* Update many things (check commit's description)

- Comments
- Terminal message
- UI Text
- TSDoc
- md docs
- Improve error messages in src\NetscriptFunctions\Cloud.ts
