Build python

[qianxichen233]

working python build script, not refined.

Update 1/23/25: Python has been built statically. It can import libraries that doesn't require dlopen. Tested with simple programs. Next step is to build Python with modules and with dynamic loading (Issue #40)

Update as of 2/26/25:
As of now, we have build_python_wasm.sh which does static build as well as installs the python within lindfs.
build_shared_python_wasm.sh uses the object files created in the static build process to create the shared python build. This shared python wasm binary is copied to lindfs/bin.

cd cpython
./build_python_wasm.sh
./build_shared_python_wasm.sh

Tested with 2 or 3 sample python programs.

To be decided:

• If we should keep both static and dynamic python binary in lindfs or not. Also should decide which folders we want them in. make install copies the static binary to lindfs/usr/local/bin. While the shared python build script currently copies dynamic binary to lindfs/bin
• Does we need both .wasm and .cwasm binaries within lindfs.
