meta-agl-bsp: remove redundant abseil-cpp patches

Remove local patches for abseil-cpp and python3-grpcio (which has a
vendored abseil-cpp) that were to fix a runtime crash on RISC-V
plaforms.  The patches have been merged into the recipes in upstream
meta-oe and meta-python, so are no longer required with the latest
bump of those layers.

Bug-AGL: SPEC-5212

-Subject: [PATCH] PR #1644: unscaledcycleclock: remove RISC-V support
-
-Imported from GitHub PR https://github.com/abseil/abseil-cpp/pull/1644
-
-Starting with Linux 6.6 [1], RDCYCLE is a privileged instruction on RISC-V and can't be used directly from userland. There is a sysctl option to change that as a transition period, but it will eventually disappear.
-
-The RDTIME instruction is another less accurate alternative, however its frequency varies from board to board, and there is currently now way to get its frequency from userland [2].
-
-Therefore this patch just removes the code for unscaledcycleclock on RISC-V. Without processor specific implementation, abseil relies on std::chrono::steady_clock::now().time_since_epoch() which is basically a wrapper around clock_gettime (CLOCK_MONOTONIC), which in turns use __vdso_clock_gettime(). On RISC-V this VDSO is just a wrapper around RDTIME correctly scaled to use nanoseconds units.
-
-This fixes the testsuite on riscv64, tested on a VisionFive 2 board.
