kselftest/arm64: mte: user_mem: test a wider range of values
Instead of hard coding a small amount of tests, generate a wider
range of tests to try catch any corner cases that could show up.
These new tests test different MTE tag lengths and offsets, which
previously would have caused infinite loops in the kernel. This was
fixed by 295cf156231c ("arm64: Avoid premature usercopy failure"),
so these are regressions tests for that corner case.
