Hold single vector for solidified file entries

[KSAlpha]

Solidified file entries are held in structs as separate members (executable, readonly, ...). We can reduce members and rendering complexity by introducing permission member inside SolidFileEntry struct.

Expected changes

Current implementation

• executable: Vec<FileEntry> -> executable: Vec<SolidFileEntry>
• readonly: Vec<FileEntry> -> readonly: Vec<SolidFileEntry>

New design

• executable: Vec<FileEntry> + readonly: Vec<FileEntry> -> file_entries: Vec<SolidFileEntry>
• New member of SolidFileEntry: permission: int
