Log Message: ----------- examples: libmetal: amd_rpu: baremetal: Use AMD recommended ISR via IPIPSU driver

AMD BSP recommended usage recommends using IPI driver to hook in IPIPSU driver.

Reference example here: https://github.com/xilinx/embeddedsw/blob/master/XilinxProcessorIPLib/driver...

As part of this remove unneeded lines.

Also use config.h provided IPI value to get the IPIPSU instance.

Log Message: ----------- examples: libmetal: align demo carveouts with OpenAMP layout

Move the libmetal host/remote demo off the legacy single 3ed80000.shm window to the OpenAMP-style carveouts at 0x09860000 with separate descriptor UIOs (9860000.shm_desc, 9864000.shm_desc) and payload (9868000.shm), update the platform init code to open/map the new descriptor regions, add optional config-driven IPI overrides, and match the RPU defaults to the same layout.

As part of this, mimic OpenAMP vendor-specific demos in that they will also support support use of unified CMake-driven symbols. This enables external tooling to generate a .cmake file from the system device tree that configures the demo for the target platform without manual edits to source files.

Key changes:

- Add config.h.in templates for both Linux host and RPU remote that use #cmakedefine to optionally override defaults from common.h

- Separate monolithic SHM_BASE_ADDR/SHM_SIZE into distinct carveouts: * SHM0_DESC_BASE/SIZE - descriptor ring 0 * SHM1_DESC_BASE/SIZE - descriptor ring 1 * SHM_PAYLOAD_BASE/SIZE - data payload area

- Wrap all platform-specific IPI symbols in #ifndef guards: * IPI_DEV_NAME, IPI_BASE_ADDR, IPI_MASK

- Wrap all platform-specific TTC symbols in #ifndef guards: * TTC_DEV_NAME, TTC0_BASE_ADDR, TTC_NODEID

- Include demo-specific specific symbols for IPI, Shared memory and TTC as provided by configure-time generated config.h file.

- Configure linker script via .cmake metadata too.

Log Message: ----------- examples: libmetal: amd_linux_userspace: simplify build

Simplify build as it was previously based off legacy Libmetal Linux AMP Demo.

Streamline it to just pick up and deliver a statically linked executable.
