Using CMD_* configs from spl doesn't make logical sense. Therefore this
patch replaces the checks for CMD_BOOTx with newly added library symbols
BOOTI, BOOTM and BOOTZ which are enabled by their respective CMD_* or
SPL_* counterparts.

SPL_BOOTZ is enabled by default for 32-bit ARM systems and SPL_BOOTI is
enabled by default for 64-bit ARM and RISCV.

The respective C files (image.c/zimage.c) are compiled based on library
symbols BOOTx instead which are in turn selected by both CMD_BOOTx and
SPL_BOOTx as required.

 * Add BOOTM for compiling boot.c
v6:
https://lore.kernel.org/u-boot/20250403215522.1284502-1-anshuld@ti.com/
Changes in v6:
 * Add LIB_BOOTx library symbols
 * Update existing configs ensuring no change in size or build failure

https://lore.kernel.org/all/20250314035505.4029331-1-anshuld@ti.com/
Changes in v5:
 * Remove imply clause for CMD_BOOTZ instead add default y for
SPL_HAS_BOOTZ
 * Update commit message to reflect the changes
 * Remove 'More info' link
v4:
https://lore.kernel.org/u-boot/20250313032842.1189977-1-anshuld@ti.com/
Changes in v4:
 * Don't set SPL_HAS_BOOTI for sandbox by default
 * Updated prompts for SPL_HAS_BOOT[IZ]
 * Removed check for SPL_HAS_FRAMEWORK from Makefile
v3:
https://lore.kernel.org/u-boot/20250312124757.789013-1-anshuld@ti.com/
Changes in v3:
 * Add imply clause for CMD_BOOTZ to enable SPL_HAS_BOOTZ
 * Fix broken check for bootz_setup
v2:
https://lore.kernel.org/u-boot/20250312094241.629707-1-anshuld@ti.com/
Changes in v2:
 * Add SPL_HAS_BOOT[IZ] configs
v1:
