docs(performance): Add esp32p4/c5 relevant information to the performance guides

in speed.rst:
- add startup time increase info when spiram test is enabled
- add startup time increase info when spiram is enabled and
  poisoning comprehensive is enabled
- add L2 cache variable size info to optimize IRAM space / cache misses
- update sections refencing bluetooth/wifi built-in tasks to not show
  related info for p4 targets.
- Add IDF_TARGET_RF_TYPE for esp32c5

in ram-usage.rst:
- add L2 cache variable size info to maximize RAM space

Remove the files from esp32c5.txt and esp32p4.txt
that are no longer in need of update.

How much time this saves depends on the binary size and the flash settings. Note that this setting carries some risk if the flash becomes corrupt unexpectedly. Read the help text of the :ref:`config item <CONFIG_BOOTLOADER_SKIP_VALIDATE_ON_POWER_ON>` for an explanation and recommendations if using this option.
    - It is possible to save a small amount of time during boot by disabling RTC slow clock calibration. To do so, set :ref:`CONFIG_RTC_CLK_CAL_CYCLES` to 0. Any part of the firmware that uses RTC slow clock as a timing source will be less accurate as a result.

     With a few exceptions, most importantly the lwIP TCP/IP task, in the default configuration most built-in tasks are pinned to Core 0. This makes it quite easy for the application to place high priority tasks on Core 1. Using priority 19 or higher guarantees that an application task can run on Core 1 without being preempted by any built-in task. To further isolate the tasks running on each CPU, configure the :ref:`lwIP task <CONFIG_LWIP_TCPIP_TASK_AFFINITY>` to only run on Core 0 instead of either core, which may reduce total TCP/IP throughput depending on what other tasks are running.
