swig: convert from autotools to cmake

Drop patches:
0001-Use-proc-self-exe-for-swig-swiglib-on-non-Win32-plat.patch
(superseded long time ago by native wrapper)

0001-configure-use-pkg-config-for-pcre-detection.patch
(autotools-specific)

Drop all autoconf options and native python dependency as cmake configuration doesn't contain those.

(From OE-Core rev: 1317b042812cc926546b05cf1e2179549ea3e5ca)
