common: Enhance memory mapping safety and debugging
- Reduce max_memory_size from 512GB to 1GB for safer allocation limits
- Add memory operation logging for debugging purposes
- Implement MapMemory() with additional safety checks and large allocation handling
- Add validation checks for memory mappings
- Introduce chunked allocation strategy for large memory requests
- Add detailed error logging for memory operations

common/nvdrv: improve memory validation and error handling
Implements several improvements to memory handling and validation:

- host_memory: Add IsValidMapping() and IsDirectMappingEnabled() methods to
  validate memory access
- host_memory: Fix virtual base offset calculation to use proper pointer
  arithmetic
- host_memory: Add size field to track allocation size
- nvhost_ctrl_gpu: Return InvalidState instead of InvalidValue for TPC mask
  buffer size validation
- Update copyright year for citron

The changes improve memory safety by adding explicit validation checks and
fixing pointer arithmetic in the virtual memory implementation.

99ceb03a1c general: Convert source file copyright comments over to SPDX
This formats all copyright comments according to SPDX formatting guidelines.
Additionally, this resolves the remaining GPLv2 only licensed files by relicensing them to GPLv2.0-or-later.

7f85abb281 common/host_memory: Implement a fallback if fastmem fails.
This falls back to the old approach of using a virtual buffer.

Windows is untested, but this build should fix support for Windows < 10 v1803. However without fastmem support at all.

c4609c92ee common/host_memory: Optimize for huge tables.
In theory, if we have 2 MB continously mapped, this should save one layer of TLB.
Let's make it at least more likely by aligning the memory.
