AK: Don't perform the shift when it's too large when decoding LEB128
...
Prior to this, we calculated whether the shift was too large for the
result, and then did the shift regardless.

AK: Handle LEB128 encoded values that are too large for the result type
...
Previously, we would go crazy and shift things way out of bounds.
Add tests to verify that the decoding algorithm is safe around the
limits of the result type.

AK: Make LEB128 capable of reading into any type
...
And not just ssize_t/size_t.
This is useful in cases where the output size is supposed to be larger
than size_t.
