ppg:devel:19: switch pg_tde source to percona/pg_tde main, add build fixes

Track the upstream percona/pg_tde repository's main branch (moving
versionformat) instead of the pinned jeltz/pg_tde pg19 fork branch.

Add the cmake BuildRequires/Build-Depends now needed to build the
libkmip cmake subproject against that source.

Port the two C++ KMIP client build fixes already applied in devel:18:

- SUSE: pull gcc-c++ into the chroot. Without it meson falls back to
  clang++ (from the llvmjit BuildRequires) for the C++ link while C is
  compiled by gcc with -flto=auto, and ld.bfd cannot combine the mixed
  LTO objects ("plugin needed to handle lto object", "archive has no
  index").

- Debian 11: quilt patch meson-cpp-std-c2a rewrites cpp_std=c++20 to
  the equivalent c++2a spelling, since bullseye's meson 0.56.2 predates
  the c++20 option name (added in meson 0.57).

+Use the pre-ratification spelling "c++2a" of the C++20 standard so that
+meson 0.56.2 on Debian 11 accepts the cpp_std value ("c++20" was only
+added to meson's cpp_std choices in 0.57). gcc and clang treat -std=c++2a
+and -std=c++20 identically, and g++ 10 on bullseye compiles the C++ KMIP
+client fine. The libkmip cmake subproject needs no change: cmake itself
+emits -std=c++2a for CMAKE_CXX_STANDARD 20 on gcc 10.
