set new encoding as true by default and allow it to be disabled (#5915)

## Description

This PR sets the "new encoding" (from now on will be called "encoding
v1") as the default. We can still disable it using `no_encoding_v1`,
which switches back to "encoding v0".

Actions that needs to be done after this being merged will exist in
#5727

New features
  - ABI Super traits;
  - AbiEncode buffer dynamic sizing;

Bugs Fixed
- `ContractCall` intrinsic interaction effect was not set correctly;

Fixing warnings and error messages
- Better error message when core-lib is not available for
scripts/contracts/predicates;
- Better error message when main inputs/outputs are unknown or error
types;
- Better error message when main inputs/outputs do not implement
AbiEncode/AbiDecode;
- Don't warn impurity attributes on the "__entry" fn;
- Don't warn CEI on the "__entry" fn. Our CEI analysis, currently, does
not recognize `Never`. This means it does not realize it is impossible
to call two contract functions;

Test Disabled (needs to be enabled again in the future)
- should_pass/language/name_resolution_after_monomorphization
- should_pass/language/shadowing/shadowed_glob_imports
- should_pass/language/name_resolution_inside_intrinsics
- sdk-harness/external_proxy test is not working. I am assuming it is
the LDC bug that is already fixed on version 0.25. What is happening is
that the literal "double_value" has the correct length, but some random
data. Which makes the method selector fails. Only after we call LDC. The
proxy contract is working.

Test generating more warnings than before
- should_pass/dca/contract/superabi_contract_calls
What happens here is that when we implement a trait for `Contract`, we
actually generate two functions: one prefixed `__contract_entry` that is
called by the method selector; and another one normal, that can be
called freely. So, if the trait method is never called manually, it is
marked as dead.
- should_pass/dca/contract/abi_fn_params
I actually think the new warning is correct and nothing here needs to be
done.

Test with fewer warnings than before
- should_pass/dca/unused_fields
auto-impl is making all fields being used. so no dead code warnings are
being generated. We need to fix this.

Changes to std-lib
- Functions that return data about call context changed the semantic.
`first_param` and `second_param` return the value as the VM sees them.
We now have `called_method` and `called_args`. This means that we can
change the protocol later and still keep these four functions always
working and with meaningful names.
- 
- predicate_data also was updated to use encoding v1 protocol.

ICE
- increase_buffer_if_needed implementation is a little bit strange
because does not work as a method inside `Buffer`. For some reason, it
is generating an ICE. I need to create an issue so we can fix, and
improve the implementation here.
- `Buffer` used by AbiEncode needs a `push_bytes` so we can be more
efficient when encoding Bytes and others.
