zqyhimself b7dc88f6ab fix(esp32-p4): split each P4 build into rev<3 + -p4x twin variants

【中文】
针对 PR #1943 的评审建议（Y1hsiaochunnn + laride）：当前市面的 ESP32-P4
几乎都是 rev v1.x / v2.x 硅片，IDF 默认 REV_MIN_301 会让 bootloader 被
bootloader.rev3.ld 链到高位 HP_SRAM，导致在存量硬件上第一条指令就 panic。
未来 ESP32-P4X（rev >= 3.x）又需要保留默认配置，因此不能在所有 P4 board
上一刀切地写死 CONFIG_ESP32P4_SELECTS_REV_LESS_V3=y。

方案：对所有 P4 config.json 的每个现有变体，添加 REV_LESS_V3 + REV_MIN_100，
并复制一份加 `-p4x` 后缀的孪生变体（不加上述两行，保持 IDF 默认 REV_MIN_301
以支持未来 P4X 芯片）。

受影响的 6 份 config.json，共 14 个原变体，复制后新增 14 个 `-p4x` 变体：
- main/boards/waveshare/esp32-p4-wifi6-touch-lcd/config.json（8 -> 16 变体，
  其中 7b 变体保留 32MB flash + custom 分区配置）
- main/boards/waveshare/esp32-p4-wifi6-touch-lcd-3.5/config.json
- main/boards/waveshare/esp32-p4-nano/config.json
- main/boards/esp-p4-function-ev-board/config.json
- main/boards/wireless-tag-wtp4c5mp07s/config.json
- main/boards/m5stack-tab5/config.json

[English]
Per review on PR #1943 (Y1hsiaochunnn + laride): almost all ESP32-P4 silicon
on the market today is rev v1.x / v2.x. IDF's default REV_MIN_301 links the
bootloader via bootloader.rev3.ld into the upper HP_SRAM window, which those
chips cannot execute; the CPU panics on the first opcode. Future ESP32-P4X
(rev >= 3.x) still needs the IDF default, so we cannot hard-code
CONFIG_ESP32P4_SELECTS_REV_LESS_V3=y across all P4 boards.

Strategy: for each existing variant in every P4 config.json, add REV_LESS_V3
+ REV_MIN_100 to target current silicon, and add a `-p4x` twin variant
without those two configs (keeping IDF default REV_MIN_301) for future P4X
chips.

Affects 6 config.json files, 14 original variants duplicated into 14 `-p4x`
twins:
- main/boards/waveshare/esp32-p4-wifi6-touch-lcd/config.json (8 -> 16
  variants; the 7b variant keeps its 32 MB flash + custom partition configs)
- main/boards/waveshare/esp32-p4-wifi6-touch-lcd-3.5/config.json
- main/boards/waveshare/esp32-p4-nano/config.json
- main/boards/esp-p4-function-ev-board/config.json
- main/boards/wireless-tag-wtp4c5mp07s/config.json
- main/boards/m5stack-tab5/config.json
