The current approach has several drawbacks. Mostly, when
cross-compiling, invoking the compiler binary directly to query the
machine hardware can behave unexpectedly depending on the toolchain
wrapper (using COMPILER_TARGET, CFLAGS, etc).
As CMake is the official tool to build llama.cpp, I propose to only rely
on it to get those variables (`CMAKE_SYSTEM_NAME` and
`CMAKE_SYSTEM_PROCESSOR`).

Previously, cmake was forcing `_WIN32_WINNT=0x0A00` for MinGW builds,
This caused "macro redefined" warnings with toolchains that define the version.
This also removes the `GGML_WIN_VER` variable as it is no longer needed.

Some toolchains do not support linking via pragmas such as:
#pragma comment(lib, "crypt32.lib")
so we need to add the library explicitly.

This change limits progress updates to approximately every 0.1% of the
file size to minimize stdio overhead.
Also fixes compiler warnings regarding __func__ in lambdas.

`FetchContent_Populate` is now deprecated and will be completely removed

We need to explicitly replace `;` with spaces from the list to make
`CMAKE_REQUIRED_FLAGS` work correctly...

`test-arg-parser.cpp` has been updated to work consistently,
regardless of whether CURL or SSL support is available, and
now always points to `ggml.ai`.
The previous timeout test has been removed, but it can be
added back by providing a dedicated URL under `ggml.ai`.

The JSON parser is temporarily kept only for backward compatibility. It
reads the etag from old .json files to prevent unnecessary re-downloads
for existing users.
This legacy code can be removed in a future version.

Introduce a new `LLAMA_OPENSSL` option, enabled by default.
This preserves the previous default (libcurl first, OpenSSL as fallback),
while allowing OpenSSL to be disabled if desired.

This change refactors the download logic to properly support offline mode
even when the project is built without CURL.
Without this commit, using `--offline` would give the following error:

When compiling with GGML_STATIC=ON, the build process would produce a
binary that was still dynamically linked to OpenMP. This defeats the
purpose of a static build:

-DLLAMA_CURL=OFF \
-DGGML_CCACHE=OFF \
-DGGML_NATIVE=OFF \

This commit resolves the issue by modifying `CMAKE_FIND_LIBRARY_SUFFIXES`
to prioritize `.a` files, forcing CMake to link the static version of
the library.
