Remove depends/install_raqm_cmake.sh; update FreeBSD instructions

[akx]

Refs #9926 (noticed while reviewing it).

Changes proposed in this pull request:

• Removes depends/install_raqm_cmake.sh, which doesn't seem to be required anymore: it was added in 2017 in 57632d5 and is only ever mentioned in the "only tested on FreeBSD 10/11" (EOL for 7 and 6 years respectively) instructions.
• Updates FreeBSD instructions and notes PIL 13.0.0dev0 is buildable from source on FreeBSD 15.1.

Removes depends/install_raqm_cmake.sh, which doesn't seem to be required anymore: it was added in 2017

#4109 removed depends/freebsd_10.sh, which used it.

For the record, why Python 3.12 and not Python 3.14?

[akx]

No such thing on this version of FreeBSD.
