misc: Remove raven-js and raven-node from master

[rhcarvalho]

We track raven-js and raven-node (v3 of JS SDKs) and release important bugfixes only from the '3.x' branch, and never from master.

Over time, the code in raven-* in master and in the 3.x branch got out of sync.

Removing raven-* from master eliminates confusion and cleans up the workspace when developing the current 5.x series of packages.

This is the result of

$ git rm -r packages/raven-js packages/raven-node

Plus changes to remove lines from a handful of files:

$ git diff --stat HEAD~2
 .gitignore    | 1 -
 lerna.json    | 1 -
 package.json  | 1 -
 tsconfig.json | 4 +---
 typedoc.js    | 2 --
 yarn.lock     | 7 -------
 6 files changed, 1 insertion(+), 15 deletions(-)

While not the most important reason for removal, it does reduce the amount of stuff in disk in a checkout.
Also makes global searches and search-replace more useful.

Before

$ git checkout master
$ du -hc $(git ls) | tail -1        # let's ignore the quoting problem missing one file in the total
du: packages/raven-node/test/fixtures/file: No such file or directory
du: with: No such file or directory
du: spaces: No such file or directory
du: in: No such file or directory
du: path.js: No such file or directory
8.6M    total

After

$ git checkout rhcarvalho/remove-raven-from-master
$ du -hc $(git ls) | tail -1
2.5M    total

Removing raven-* brings us to a checkout which is 29% of the previous size.
A reduction of over 70% 😄

Cancelled the BrowserStack job since it should be irrelevant here. All the other jobs are green.
