feat(build): set CRYPTO_SUPPORT macro per BL

Moving the setting of CRYPTO_SUPPORT from the main Makefile to
individual component makefiles using the new build macro
make_defines for each BL-specific CPPFLAGS.

Rework romlib build command to use CRYPTO_LIB to determine mbedtls need
instead of CRYPTO_SUPPORT. If CRYPTO_SUPPORT is set for any component,
then CRYPTO_LIB will be filled, romlib can use this instead.

Add a convenience makefile macro for setting CRYPTO_SUPPORT from
component specific makefiles, have components call the macro based on
whether authenication verification (NEED_AUTH) and/or hash calculation
(NEED_HASH) is required for the specific boot stage.

refactor(build): make sorting of sections generic

All BLs define essentially the same sequence for sorting of sections.
Make that generic so it applies more easily.

The toolchain refactor change introduces the `${toolchain}-${tool}-id`
variables, which provide identifiers for all of the toolchain tools used
by the build system. This change replaces the various conditions that
are in use to identify these tools based on the path with a standard set
of comparisons against these new identifier variables.

This change migrates the values of `CC`, `CPP`, `AS` and other toolchain

equivalent to the values that they're replacing.

build: clarify linker script generation

The following build system variables have been renamed:

- `LINKERFILE` -> `DEFAULT_LINKER_SCRIPT`
- `BL_LINKERFILE` -> `DEFAULT_LINKER_SCRIPT_SOURCE`
- `<IMAGE>_LINKERFILE` -> `<IMAGE>_DEFAULT_LINKER_SCRIPT_SOURCE`

These new names better reflect how each variable is used:

1. the default linker script is passed via `-dT` instead of `-T`
2. linker script source files are first preprocessed

Additionally, linker scripts are now placed in the build directory
relative to where they exist in the source directory. For example,
the `bl32/sp_min/sp_min.ld.S` would now preprocess to
`sp_min/sp_min.ld` instead of just `bl32.ld`

BREAKING-CHANGE: The `LINKERFILE`, `BL_LINKERFILE` and
`<IMAGE_LINKERFILE>` build system variables have been renamed. See the
commit message for more information.

FWU: Add Generic BL2U FWU image support in BL2

The Firmware Update (FWU) feature needs support for an optional
secure world image, BL2U, to allow additional secure world
initialization required by FWU, for example DDR initialization.

This patch adds generic framework support to create BL2U.

NOTE: A platform makefile must supply additional `BL2U_SOURCES`
to build the bl2u target. A subsequent patch adds bl2u
support for ARM platforms.
