wasm32-wasi has been removed in Rust 1.84 (Jan 5th, 2025). if one
compiles the tree with Rust 1.84 or up, following build failure is
expected:
```

error: Error loading target specification: Could not find specification for target "wasm32-wasi". Run `rustc --print target-list` for a list of built-in targets
```
in order to workaround this issue, let's check for supported target,
and use wasm32-wasip1 if wasm32-wasi is not listed as the supported
target.

The currently used versions of "time" and "rustix" depencies
had minor security vulnerabilities.
In this patch:
- the "rustix" crate is updated
- the "chrono" crate that we depend on was not compatible
with the version of the "time" crate that had fixes, so
we updated the "chrono" crate, which actually removed the
dependency on "time" completely.
Both updated were performed using "cargo update" on the
relevant package and the corresponding version.
Fixes#15772Closesscylladb/scylladb#16378
instead of checking the availability of a required program, let's
use the `REQUIRED` argument introduced by CMake 3.18, simpler this
way.

as an alternative to passing the link-args using the environmental variable,
we can also use build script to pass the "-C link-args=<FLAG>" to the compiler.
see https://doc.rust-lang.org/nightly/cargo/reference/build-scripts.html#cargorustc-link-argflag
to ensure that cargo is called again by ninja, after build.rs is
updated, build.rs is added as a dependency of {wasm} files along with
Cargo.lock.
this change is verified using following command
```
RUSTFLAGS='--print link-args' cargo build \
--target=wasm32-wasi \
--example=return_input \
--locked \
--manifest-path=Cargo.toml \
--target-dir=build/cmake/test/resource/wasm/rust
```
the output includes "-zstack-size=131072" in the argument passed to lld:

with this change, it'd be easier to build .wat files in CMake, so
we don't need to repeat the settings in both configure.py and
CMakeLists.txt

we compile .wat files from .rs and .c source files since
6d89d718d9.
these .wat are used by test/cql-pytest/test_wasm.py . let's update
the CMake building system accordingly so these .wat files can also
be generated using the "wasm" target. since the ctest system is
not used. this change should allow us to perform this test manually.

This is a translation of Cassandra's CQL unit test source file
validation/entities/UFTypesTest.java into our cql-pytest framework.
There are 7 tests, which reproduce one known bug:
Refs #13746: UDF can only be used in SELECT, and abort when used in WHERE, or in INSERT/UPDATE/DELETE commands
And uncovered two previously unknown bugs:
Refs #13855: UDF with a non-frozen collection parameter cannot be called on a frozen value
Refs #13860: A non-frozen collection returned by a UDF cannot be used as a frozen one
Additionally, we encountered an issue that can be treated as either a bug or a hole in documentation:
Refs #13866: Argument and return types in UDFs can be frozen
Closes#13867
After recent changes, we are able to store only the
C/Rust source codes for Wasm programs, and only build
them when neccessary. This patch utilizes this
opportunity by removing most of the currently stored
raw Wasm programs, replacing them with C/Rust sources
and adding them to the new build system.
