Problem:
1. In low-memory scenarios, the dynamic buffer feature can fail due to memory fragmentation.
2. It requires a contiguous 16KB heap chunk, but continuous allocation and deallocation of
the RX buffer can lead to fragmentation.
3. If another component allocates memory between these operations, it can break up the
available 16KB block, causing allocation failure.
Solution:
1. Introduce configurable strategy for using dynamic buffers in TLS connections.
2. For example, convert RX buffers to static after the TLS handshake.
3. Allow users to select the strategy via a new field in the esp_http_client_cfg_t structure.
4. The strategy can be controlled independently for each TLS session.
When parsing ND-JSON streams, this is needed to indicate the
point when the ND-JSON stream is considered open, which
occurs just after the last HTTP_EVENT_ON_HEADER.
ND-JSON stream clients cannot rely on the first HTTP_EVENT_ON_DATA,
since that is only triggered by an event, which are optional and
may never be sent, or only sent well after the last HTTP_EVENT_ON_HEADER.
Closes#15952
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.

Refactor examples to build with MBEDTLS_CERTIFICATE_BUNDLE disabled. Only examples
that can work with certificate bundle disabled have been modified here.
- This allows to easily test example with different public servers
- Flash footprint impact is limited due to selection of only most common
certs from bundle.
- Allows users to manually intercept and process the HTTP redirection
when disable_auto_redirect (from the esp_http_client handle) is set to true

Replaced hyphens with underscores in examples
project definition for all examples which had
hyphens in their project name. dpp-enrollee is
an exceptions because the name matches the
project directory name while the project
directory also contains hyphens.
esp_netif_init() returns standard esp_err_t error code (unlike tcpip_adapter init), so shall be checked for the return value
Also to make the initialization code more consistent.
