[DB] Increase max length of link fields

The current core supports links with the maximum length of 256 chars in
header links of tt_content elements and links in table
sys_file_reference.

External links can have much more than 256 chars.

Increasing the maximum length to 1024 should be enough - even current
browsers are supporting much more than 1024 chars.

Revert "[BUGFIX] Fix JavaScript error that prevents links to anchor tags in RTE"

This reverts commit 9bcebec002224bbc2a0dcd38cff032a14f2e075e.

The commit message of the original patch references a wrong
issue number and the target versions seem to be wrong too.

[TASK] Fix functional tests for EXT:impexp

After issue #61944 has been merged, sys_file_reference.link does
not support NULL values anymore (which is fine). However, in the
past the default has been NULL and also has been written in the
accordant functional test data assertions.

Thus, NULL assertions are removed from the test. The change of
the "size" property by 5 bytes can be explained by a difference
in serializing NULL values and serializing an empty string.
