[v3,1/2] package/pkg-meson: separate infrastructure logic from package

Move all logic related to handling meson packages to the
package/pkg-meson file. This now mirrors the other build
systems and keeps the package itself clean.

Correctly prefix variables with PKG_MESON_

v2->v3:
-   rebase, split up the moving

v1->v2:
-   squash 2 commits, really hard to separate as moving and renaming
    variables from 2 to one location affects alot code.
-   use TOOLCHAIN_POST_INSTALL_STAGING_HOOKS again.
-   consistently use double quotes for sed patterns

  I moved all this to the beginning of the file, since it's (indirectly) used 
within inner-meson-package.

  Applied to master with that changed, thanks.
