Mazdak Farrokhzad 8544e6cf02 Add Hash indices (#3976 )

# Description of Changes

Fixes https://github.com/clockworklabs/SpacetimeDB/issues/1122.

Adds hash indices and exposes them through `#[index(hash)]` for Rust
modules,
with support for typescript and C# to come in follow ups.
On the client/sdk side, for now, any index is backed via a BTree/native
index as it is the most general.

A hash index may only be queried through point scan and never ranged
scans.
Attempting a ranged scan results in an error, with the mechanism
implemented in the previous PR
(https://github.com/clockworklabs/SpacetimeDB/pull/3974).



# API and ABI breaking changes

None

# Expected complexity level and risk

2?

# Testing

A test for ensuring that hash indices cannot be used for range scans is
added.
Tests exercising hash indices will come in the next PR.
