feat: refactor UART and Timer Interfaces; Remove Unused Components

Browse Source 
- Deleted the UART interface and related components from the RTL design, including the UART TX/RX signals and instances.
- Removed the timer interface and its associated files from the project, including the timer definitions and references in the integration files.
- Updated the APB target configurations to reflect the removal of the UART and timer components, ensuring the IRQ and memory map configurations are consistent.
- Adjusted the formal verification properties and testbenches to exclude references to the removed components.
- Cleaned up the integration documentation to accurately describe the current state of the system without the UART and timer interfaces.

`irq_vector_width`, `irq_groups`, and `interrupts` define the complete core
interrupt topology. `rib` and `apb` group entries declare the wrapper output
width and the associated `retrosoc.sv` signal. Every group bit must be present
exactly once, each core-vector bit must have one source, and sources are limited
to scalar signal references or one-bit constants. The generator emits the two
wrapper bindings, the core-vector wiring, and simulation-only assertions. Core
IRQ bits 0 through 16 retain their current compatibility mapping; additions
must use currently unallocated bits and preserve the existing entries. Bits
without an interrupt entry are driven low. Firmware does not expose a generic
