Linux 6.19 compat: in-tree build: fix duplicate GCM assembly functions

Browse Source 
Linux 6.19 added an AES-GCM VAES-AVX2 assembly implementation. It's
basically a translation from the BoringSSL perlasm syntax to macro
assembly. We're using the same source but the perlasm generated flat
assembly which shares some global function names with the former.
When  building in-tree this results in the linker failing due to the
duplicate symbols.

To avoid the error we prepend `icp_` via a macro to our function
names.
