pc: update wifi driver The driver falls in line with the previous 'legacy_wifi_drv' component where the ported wireless LAN stack and device driver is encapsulated in a library. This library in return is used by the 'Libc::Component' providing the necessary environment for the 'wpa_supplicant'. In constrast to the old driver a 'wifi' VFS plugin is in charge of initalizing the 'Lx_kit::Env' prior to executing any static constructors. Fixes #4455.

lx_emul & wireguard & wifi: centralized random.cc Both the Wifi driver and the WireGuard port used local implementations for their source of randomness. Wifi used a Xoroshiro128+ PRNG for rapid generation of random values but initialized this PRNG always with the same static seed value. WireGuard, in contrast, requested each random byte directly from the jitterentropy lib, which is considered to be very time intensive. This commit removes the local variants of random.cc and introduces a new centralized lx_emul/random.cc . The new variant combines the former approaches, so, that jitterentropy is accessed only in order to generate a random seed for a Xoroshiro128+ PRNG. Front-end requests for random values are then fulfilled efficiently via the PRNG. :Warning: The output of the Xoroshiro128+ PRNG that is used in the new implementation of the lx_emul randomness functions has known statistical problems (see https://en.wikipedia.org/wiki/Xoroshiro128%2B#Statistical_Quality). Furthermore, the integration of Xoroshir128+ with the lx_emul code was not reviewed/audited for its security-related properties, so far, and has the known deficiency of seeding the PRNG only once during initialization. Thus, we strongly advise against the use of the lx_emul randomness functions for security-critical purposes. Ref #4397

pc: consoldiate LX emul of current drivers This commit de-duplicates the redundant dummy implementations and to some degree also the 'lx_emul.c' implementations while also decluttering the various 'dep.list' files. The code is moved into 'src/lib/pc/lx_emul' where it becomes part of the 'pc_lx_emul' library. Fixes #4500.
