edk2-firmware-tegra: add support for JetsonMinimal builds

Browse Source 
The AGX Orin platform supports a minimal UEFI for booting
off its internal eMMC. Add support for a TEGRA_UEFI_MINIMAL
variable, which when set to a boolean true value, builds
this minimal configuration instead of the normal UEFI.

See the "miniUEFI Support" section in the Jetson Linux developer
guide for more information about support, restrictions, etc.
