Add @phan- prefixes for recognized doc tags

The following prefixes are added:

* `@phan-assert`
* `@phan-assert-if-false`
* `@phan-assert-if-true`
* `@phan-extends`
* `@phan-inherits`
* `@phan-method`
* `@phan-mixin`
* `@phan-param`
* `@phan-property`
* `@phan-property-read`
* `@phan-property-write`
* `@phan-real-return`
* `@phan-return`
* `@phan-template`
* `@phan-type`
* `@phan-var`

No changes to any of the parsing were made, as the syntaxes seem to
match what's already done for the existing unprefixed tags and/or the
existing `@psalm-` and `@phpstan-` prefixed tags.
