Change default file format to 1.8 (#5949)

Browse Source 
Change default file format to 1.8 across various tests and examples, updating file creation and access logic accordingly.

Behavior:
Default file format version changed to 1.8 in H5Pfapl.c.
Updated file creation and access to use 1.8 format in h5ex_g_compact.c and test_file_image.c.
Set earliest file format in multiple test files including cache_tagging.c, dtypes.c, and links.c.
Tests:
Modified expected output in tools/test/misc/expected/*.ls files to reflect new file format locations.
Adjusted test logic in test_file_image.c and cache_tagging.c to accommodate format changes.
Misc:
Added comments and TODOs for future format testing in test_file_image.c.
Minor variable renaming for clarity in test_file_image.c.
