feat: Support passing extra args to pip install

[LironEr]

Description

Added support to pass extra arguments to pip install command

{
  path                   = "src/python-app1",
  pip_requirements       = true,
  pip_install_extra_args = ["--platform", "manylinux2014_aarch64", "--only-binary", ":all:"]
}

Motivation and Context

Due to limitations with our CI, we can't use docker when installing and zipping requirements.
To overcome this we use the platform flag when running pip install to download the right distribution per lambda architecture.
