feat: add new parser events and rename 'onTagName' to 'onOpenTagName'.

[DylanPiercey]

Description

Instead of </div> being processed in the single onCloseTag event it is broken into the following segments

onCloseTagStart

</

onCloseTagName

div

onCloseTagStart

>

For consistency, the onTagName event was renamed to onOpenTagName and a new onOpenTagStart even was added which matches the open < bracket.

Note:

onOpenTagStart, onCloseTagStart & onCloseTagName are exclusively called for html mode tags.
All of the other events are called for concise tags as well. Eg a concise tag will get onCloseTagEnd, which shows where the tags body content stops, but will not get an onCloseTagStart or onCloseTagName.

Motivation and Context

While working on the language server is was discovered that providing completions for the closing tag could be improved if we were to split up it's events so it could be processed earlier.
