boot/ti-k3-r5-loader: add BR2_TARGET_TI_K3_R5_LOADER_USE_BINMAN option

Browse Source 
Recent version of U-Boot use binman to provide a mechanism for building
images, from simple SPL + U-Boot combinations, to more complex
arrangements with many parts.

This tool uses additional host python modules that must be provided by
Buildroot. So introduce a new option
BR2_TARGET_TI_K3_R5_LOADER_USE_BINMAN to add additional host packages
in U-Boot build dependency to use binman.

When BR2_TARGET_TI_K3_R5_LOADER_USE_BINMAN is set, BINMAN_INDIRS
environment variable to provide the directory to search for binary
blobs and select the packages required by binman. Make sure that
ti-k3-boot-firmware package has been installed before building
ti-k3-r5-loader in order to provide such firmwares.

The BR2_TARGET_TI_K3_R5_LOADER_USE_BINMAN option is currently needed
since we are in the middle of the process to switch TI AM62 and AM64
board defconfig to binman. Keep BR2_TARGET_TI_K3_R5_LOADER_USE_BINMAN
disabled for them until the u-boot/ti-k3-r5-loader version bump to
2024.01.

The dependency of binman is not really easy to follow. First we have
the packages list from binman.rst [1] then we have to install
additional python modules [2]. Maybe in the future it will be
necessary to add host-lzma and host-lz4 in the dependencies list.
