[hle] support passing arguments to homebrew applications (#4013)

Homebrew (.NRO) program args support

Adds a 'program_args' setting and delivers it to NRO homebrews via libnx's homebrew ABI. NROs previously had no way to receive CLI flags (e.g. NZ:P's -noglsl).

Setting: program_args, Category::System, startup-only.
Surfaced in Qt + Android Debug sections.

NRO loader: builds a 4-entry 'ConfigEntry' table + argv at the data segment tail; prepends 'homebrew ' so user args land at argv[1]; scans for 'svc #7' to use as LR. Drops the stale NSO-style argdata append.

KProcess: stores loader-provided guest addresses; 'Run' switches to the homebrew entry (x0=config_ptr, x1=-1, lr=svc7) and patches the real MainThreadHandle into the ConfigEntry slot. Legacy NSO path unchanged.

Tested on NZP — args reach 'argv' correctly.
