feat(indent): support TSTypeAliasDeclaration

[shixianqin]

The current indent rule does not handle the TSTypeAliasDeclaration node, resulting in inconsistent indentation for this syntax.

This PR adds an invalid test case to the indent._ts_.test.ts file to demonstrate the issue, and fixes the rule logic to properly indent TSTypeAliasDeclaration nodes.

I've added some cases. Would you be willing to try to fix them?

The equal operator token in the VariableDeclarator nodes are ignored for some reason.
This is the related issue: eslint/eslint#8546.
So we may need to discuss how to fix it compatibly and do it in a new PR.
