13a8fde3ad Implement MapPhysicalMemory/UnmapPhysicalMemory
This implements svcMapPhysicalMemory/svcUnmapPhysicalMemory for Yuzu,
which can be used to map memory at a desired address by games since
3.0.0.

It also properly parses SystemResourceSize from NPDM, and makes
information available via svcGetInfo.

This is needed for games like Super Smash Bros. and Diablo 3 -- this
PR's implementation does not run into the "ASCII reads" issue mentioned
in the comments of #2626, which was caused by the following bugs in
Yuzu's memory management that this PR also addresses:
* Yuzu's memory coalescing does not properly merge blocks. This results
  in a polluted address space/svcQueryMemory results that would be
  impossible to replicate on hardware, which can lead to game code making
  the wrong assumptions about memory layout.
  * This implements better merging for AllocatedMemoryBlocks.
* Yuzu's implementation of svcMirrorMemory unprotected the entire
  virtual memory range containing the range being mirrored. This could
  lead to games attempting to map data at that unprotected
  range/attempting to access that range after yuzu improperly unmapped
  it.
  * This PR fixes it by simply calling ReprotectRange instead of
    Reprotect.

b550a01f74 program_metadata: Add function to load meta from raw parameters
Needed for KIP loading as KIPs do not have an NPDM but do have the essential parts of the data within.

37b23efece file_sys/program_metadata: Remove obsolete TODOs
BitField has been trivially copyable since
e99a148628, so we can eliminate these
TODO comments and use ReadObject() directly instead of memcpying the
data.

9aa68212d9 file_sys/program_metadata: Print out more descriptive address space descriptions
Provides extra information that makes it easier to tell if an executable
being run is using a 36-bit address space or a 39-bit address space.
While we don't support AArch32 executables yet, this also puts in
distinguishing information for the 32-bit address space types as well.

002ae08bbd kernel/process: Hook up the process capability parser to the process itself
While we're at it, we can also toss out the leftover capability parsing
from Citra.

75603b005b process/vm_manager: Amend API to allow reading parameters from NPDM metadata
Rather than hard-code the address range to be 36-bit, we can derive the
parameters from supplied NPDM metadata if the supplied exectuable
supports it. This is the bare minimum necessary for this to be possible.

The following commits will rework the memory code further to adjust to
this.

05ef9dfc10 file-sys: Default heavy-weight class destructors in the cpp file
Several classes have a lot of non-trivial members within them, or don't
but likely should have the destructor defaulted in the cpp file for
future-proofing/being more friendly to forward declarations.

Leaving the destructor unspecified allows the compiler to inline the
destruction code all over the place, which is generally undesirable from
a code bloat perspective.

a813c10e1c file_sys: Replace includes with forward declarations where applicable
Cuts down on include dependencies, resulting in less files that need to
be rebuilt when certain things are changed.

general: Make formatting of logged hex values more straightforward
This makes the formatting expectations more obvious (e.g. any zero padding specified
is padding that's entirely dedicated to the value being printed, not any pretty-printing
that also gets tacked on).
