Szymon Malewski cb8e11653f test/alternator: Number normalization tests ...

DynamoDB normalizes Number values, so different string representations
of the same number (e.g., "1000" vs "1e3") should be treated as the
same value in all contexts.
In Alternator this is true in most cases, thanks to implicit normalization in
Decimal `to_string()` function.
However this is fragile - and in fact this function should be fixed
due to OOM vulnerability in CQL use (#8002).

This patch adds tests that should prevent regression in cases
that work currently.

Unfortunately not all contexts work currently - mainly the HASH keys
are not normalized and backend handles them by byte representation.
Added test replicate this incorrect behaviour

All added tests pass with DynamoDB, with one exception: weirdly
DynamoDB doesn't recognise unnormalized numbers in BatchGetItem
 as duplicate keys.
