Summary
I noticed when playing with the extension that ty always reparses all AST nodes
after I changed the open files in the editor.
The reason for this is that
check_file_impldepends ondb.open_filesto check if it should evict the AST or not. However, that means that all
project files will be rechecked after changing the open project files.
This PR prevents this by moving the AST eviction out of the
check_file_implfunction. This has the downsidethat it requires an extra
parsed_modulecall but thatshould be relatively cheap (we make thousends of those when checking a single file).
Test Plan
I verified that opening an other file doesn't result in re-checking every single project file.
