[gcc] Move a patch to the bundled experimental patches

As mentioned in #1908, we should have patches that are experimental
under the CT_EXPERIMENTAL option. This an experimental patch to gcc:

https://gcc.gnu.org/pipermail/gcc-patches/2022-August/600452.html

And since it may affect production toolchains, we should move this patch
to the experimental bundled patches introduced in the previous commit.

-Subject: [PATCH 9/9] picolibc: Add custom spec file fragments for using
- picolibc
-
-The '--oslib=' option allows targets to insert an OS library after the
-C library in the LIB_PATH spec file fragment. This library maps a few
-POSIX APIs used by picolibc to underlying system capabilities.
-
-The '--crt0=' option allows targets to use an alternate crt0 in place
-of the usual one as provided by Picolibc.
-
-For example, picolibc provides 'libsemihost' and 'crt0-semihost.o' on
-various targets which maps some POSIX APIs to semihosting capabilities
-and signals the semihosting environment when 'main' returns. These
-would be used by specifying --oslib=semihost --crt0=semihost.
-
-This patch also takes advantage of the IN_GPP conditional when
-building g++ to elide exception handling contents from the executable
-when not linking with the g++ driver.
