docs: Fix a few typos

There are small typos in:
- docs/oauth1/security.rst
- docs/oauth2/grants/custom_grant.rst
- oauthlib/oauth2/rfc6749/clients/backend_application.py
- oauthlib/oauth2/rfc6749/clients/base.py
- oauthlib/oauth2/rfc6749/clients/legacy_application.py
- oauthlib/oauth2/rfc6749/clients/service_application.py
- oauthlib/oauth2/rfc6749/clients/web_application.py
- oauthlib/oauth2/rfc6749/endpoints/revocation.py
- oauthlib/oauth2/rfc6749/parameters.py
- oauthlib/openid/connect/core/grant_types/dispatchers.py

Fixes:
- Should read `parameters` rather than `paramters`.
- Should read `instantiate` rather than `instanciate`.
- Should read `successfully` rather than `sucessfully`.
- Should read `present` rather than `pressent`.
- Should read `parameter` rather than `paramater`.
- Should read `efficient` rather than `effecient`.
