iOS: Fix multiple issues with PVRTC import, disable ETC1

Browse source 
Fixes: #28683, #28621, #28596 and maybe others

For iOS we enable pvrtc feature by default for both GLES2/GLES3
Etc1 for iOS doesn't have any sense, so it disabled.
Fixed checks in export editor.
Fixed pvrtc ability detection in GLES2 driver.
Fixed pvrtc encoding procedure.
