tests: generate test resources for reftables

Generate test resources for reftables. These resources are basically the
Git repositories we already have, but converted to use the "reftable"
format. For most of the part, this conversion is done by executing `git
refs migrate`.

A couple notes:

  - This require a recent Git upstream version with not-yet-upstreamed
    patches due to a bug in `git refs migrate` with reflogs.

  - The migration command does not yet support repositories with
    worktrees. Those were converted by first removing the worktrees,
    migrating the refs and then recreating them.

  - The HEAD_TRACKER reference in testrepo.git is not recognized as a
    root ref and is thus not automatically migrated.

  - testrepo.git has an empty reflog for refs/heads/with-empty-log that
    does not get migrated.

+# Test file from gitattributes(5) example:
+
+If you have these three gitattributes file:
+
+   (in $GIT_DIR/info/attributes)
+
+	a*      foo !bar -baz
+
+	(in .gitattributes)
+	abc     foo bar baz
+
+	(in t/.gitattributes)
+	ab*     merge=filfre
+	abc     -foo -bar
+	*.c     frotz
+
+the attributes given to path t/abc are computed as follows:
+
+1. By examining t/.gitattributes (which is in the same directory as the path
+   in question), git finds that the first line matches. merge attribute is
+   set. It also finds that the second line matches, and attributes foo and
+   bar are unset.
+2. Then it examines .gitattributes (which is in the parent directory), and
+   finds that the first line matches, but t/.gitattributes file already
+   decided how merge, foo and bar attributes should be given to this path,
+   so it leaves foo and bar unset. Attribute baz is set.
+3. Finally it examines $GIT_DIR/info/attributes. This file is used to
+   override the in-tree settings. The first line is a match, and foo is set,
+   bar is reverted to unspecified state, and baz is unset.
+
+As the result, the attributes assignment to t/abc becomes:
+
+	foo     set to true
+	bar     unspecified
+	baz     set to false
+	merge   set to string value "filfre"
+	frotz   unspecified
