This bump is required by `TransactionHost` coming next.
There have been many changes to `nim-evmc` since earlier developments on
`nimbus-eth1`. The types in the API have changed, and there is no longer a
need to cast the function types.
This commit bumps the submodule while keeping with EVMC API 7.5 for now.
`.gitmodules` is updated to follow the module branch `api-version-7.5`.
Submodule changes:
> Nim: Function casts no longer required, type-checking finally works
> Nim: Make the test host use exactly the type signatures in the API
> add github action script
> Nim: Export `evmc_create_vm_name_fn`
> Nim: Use `var` instead of `ptr` for arguments that are pass-by-ref
> Nim: Fix missing `ptr` in signature of `execute`
> Nim: Use `ptr` in `release` for API consistency
> Nim: Disable "Imported and not used" warning in test program
> Nim: Remove unnecessary exports from the Nim example host/VM
> Nim: Simplify Nim C++ codegen bug workaround
> Nim: Add type and documentation for `evmc_create_example_fn`
> Nim: Workaround Nim compiler bug with Nim 1.2.10
> Nim: Workaround Nim compiler bug with `uint32`-sized bitset
> Nim: Use a more varied bit pattern in `get_capabilities` test
> Nim: Convert `evmc_capabilities` to Nim bitset
> Nim: Convert `evmc_flags` to Nim bitset
> Nim: Compile time verify that target C enums are `int` sized
> Nim: Recognise that target C enums are not always `cint`
> Nim: Make `evmc_status_code` a normal enum
> Nim: Use `csize_t` in test program and Nim example host/VM
> Nim: Use `csize_t` in the VM support API
> Nim: Use `csize_t` in appropriate places to match EVMC API
> Nim: Use binary-compatible C99 `bool` without target assumptions
> Version (README): Announce we support EVMC 7.5.0 and Istanbul fork
> Doc: Tweak GitHub badges on README

> The EVMC package expects C++14 now
> Upgrade C++ `example_host` in `tests/evmc_c` to EVMC 7.5.0
