Enable CONFIG_ANON_VMA_NAME

**What I'd like:**
It would be nice to have the kernel option `CONFIG_ANON_VMA_NAME` enabled in Bottlerocket kernels. This option lets programs name anonymous memory mappings (for example, see [`decorate_maps`](https://www.gnu.org/software/libc/manual/html_node/Memory-Related-Tunables.html) in Glibc or the similar [Go feature](https://go.dev/doc/go1.25#vma-names-on-linux)), which helps to troubleshoot memory allocation issues.

**Any alternatives you've considered:**
N/A

Start in the bottlerocket-kernel-kit repository by locating the kernel configuration used to build Bottlerocket kernels and checking the current value of CONFIG_ANON_VMA_NAME. The work is done when the option is enabled in the relevant kernels and the kernel build or validation process confirms the configuration is accepted.
