Trusted Types compatibility: use DOM API for creating HTML elements instead of string concatenation in inspectTokens.ts

[annkamsk]

The next step in resolving #103699. It aims to replace construction of HTML elements by string concatenation in src/vs/editor/standalone/browser/inspectTokens.ts file. The code contains mainly a table construction by concatenating strings of <tr><td class=”foo”>foobar</td><td class=”bar”>barfoo</td></tr>. The goal is to replace them all with dom.ts#$ function calls.
