Enhance EJS formatting functionality with new placeholder handling and text tag collapsing

This commit introduces several improvements to the EJS formatting logic in the `templateformatter.js` file. It adds new regex patterns for inline placeholders and text-only tags, enhancing the ability to manage EJS content. The `maskEjsBlocks` function is updated to differentiate between control and inline EJS tags, while the `restoreEjsBlocks` function now handles both comment and inline placeholders. Additionally, a new function, `collapseTextOnlyTags`, is introduced to ensure that text content within tags is properly formatted without unnecessary whitespace. Corresponding tests have been added to verify these enhancements, improving the overall template content formatting capabilities.
