Apply configured CXXFLAGS to Python bindings

[pragnyanramtha]

Summary

• include $(AM_CXXFLAGS) in all Python binding target CXXFLAGS
• preserve existing Python include paths while applying configured warning, debug, and optimization flags
• keep the default core library build unchanged

Verification

• ./autogen.sh
• ./configure --with-python=3
• make V=1
• git diff --check

The patched Python binding compile and link commands now include -W -Wall -pedantic -Wno-long-long -g -O3.

Addresses #4.

Pull request overview

Applies the project's configured CXXFLAGS (via $(AM_CXXFLAGS)) to the Python binding library targets so warning, debug, and optimization flags are propagated to their compile commands, while preserving the existing Python include paths.

Changes:

• Prepend $(AM_CXXFLAGS) to libpy3neurosim_la_CXXFLAGS.
• Prepend $(AM_CXXFLAGS) to libpy2neurosim_la_CXXFLAGS.
• Prepend $(AM_CXXFLAGS) to the versionless libpyneurosim_la_CXXFLAGS.
