 video_core/memory_manager: Avoid repeated unnecessary page slot lookups 

GPU: Allow using R16F as a render target format.

Adds the basic skeleton for the grc:c service based off the information
provided by Switch Brew.

Adds the skeleton for the nim services based off information from Switch
Brew.

Adds ldn services based off information provided by Switch Brew.

service/lm: Minor changes

Implement R16_G16

service: Add ldr services

service: Add erpt and eupld services

service/nifm: Deduplicate interface code

Adds the skeleton for the ldr-related services based off the information
provided on Switch Brew.

This isn't used directly outside of this translation unit, so we can
hide it from external use.

Amends these to match the information on Switch Brew.

Adds the skeleton for the eupld services based off information on Switch
Brew.

Avoids copies from being made, since the string is only ever used for
lookup, the data is never transfered anywhere.

Ideally, we'd use a std::string_view here, but devices is a
std::unordered_map, not a std::map, so we can't use heterogenous lookup
here.

Avoids unnecessary reference count increments and decrements.

In one case, we don't need to make a shared_ptr copy at all,
just to call a member function.

Rather than having the same code for each nifm service variant, we can
centralize it on one class and get rid of a bit of extra code.
