Autocomplete rsx (#2421)

* autocomplete rsx

* hide the completions module

* fix autocomplete for identifiers that start with a raw identifier

* add field completion hints for props

* remove extra import

* Revert "add field completion hints for props"

This reverts commit 194899c73783e0f9b5d601d53365746d838f2048.

* fix autocomplete inside raw expressions

* fix autofmt

* feat: just use regular ifmt if it's compatible

reuses the tokens for ifmt so RA provides its HIR lowering on simple formatted strings

* fix merging ifmt strings

* add a better error message for components called like functions
