Replace howsmyssl.com with letsencrypt.org in the https_x509_bundle
example. howsmyssl.com is a third-party server that is frequently
unreachable from CI, causing flaky test failures. letsencrypt.org
chains to the same ISRG Root X1 CA, so the custom certificate bundle
validation coverage is identical.
Since letsencrypt.org was already present in the full bundle URL list,
remove the duplicate entry and reduce MAX_URLS from 9 to 8. All 6
unique root CAs in the stress test are still covered.
For the QEMU stress test, increase per-connection timeout from 30s to
60s and final completion timeout from 60s to 180s. QEMU emulated
network is 3-5x slower than real hardware for TLS handshakes.
Add flaky markers to hardware tests to handle intermittent CI lab DHCP
failures that affect all Ethernet-based tests.
Currently, several examples do not explicitly state their component
dependencies, relying instead on the default behavior that includes all
registered components and commonly required ones in the build.
Explicitly adding component dependencies can reduce build time when
set(COMPONENTS main) is used.

Adds the ESP certificate bundle feature that enables users to bundle a
root certificate bundle together with their application.
Default bundle includes all Mozilla root certificates
