Compute: build rdkit without freetype support (#6495)

## Problem
`rdkit` extension is built with `RDK_BUILD_FREETYPE_SUPPORT=ON` (by
default), which requires a bunch of additional dependencies, but the
support of freetype fonts isn't required for Postgres.


With `RDK_BUILD_FREETYPE_SUPPORT=ON`:
```
ldd /usr/local/pgsql/lib/rdkit.so
	linux-vdso.so.1 (0x0000ffff82ea8000)
	libfreetype.so.6 => /usr/lib/aarch64-linux-gnu/libfreetype.so.6 (0x0000ffff825e5000)
	libboost_serialization.so.1.74.0 => /usr/lib/aarch64-linux-gnu/libboost_serialization.so.1.74.0 (0x0000ffff82590000)

	libstdc++.so.6 => /usr/lib/aarch64-linux-gnu/libstdc++.so.6 (0x0000ffff82387000)
	libm.so.6 => /lib/aarch64-linux-gnu/libm.so.6 (0x0000ffff822dc000)
	libgcc_s.so.1 => /lib/aarch64-linux-gnu/libgcc_s.so.1 (0x0000ffff822b8000)
	libc.so.6 => /lib/aarch64-linux-gnu/libc.so.6 (0x0000ffff82144000)
	libpng16.so.16 => /usr/lib/aarch64-linux-gnu/libpng16.so.16 (0x0000ffff820fd000)
	libz.so.1 => /lib/aarch64-linux-gnu/libz.so.1 (0x0000ffff820d3000)
	libbrotlidec.so.1 => /usr/lib/aarch64-linux-gnu/libbrotlidec.so.1 (0x0000ffff820b8000)
	/lib/ld-linux-aarch64.so.1 (0x0000ffff82e78000)
	libbrotlicommon.so.1 => /usr/lib/aarch64-linux-gnu/libbrotlicommon.so.1 (0x0000ffff82087000)
```

With `RDK_BUILD_FREETYPE_SUPPORT=OFF`:
```
ldd /usr/local/pgsql/lib/rdkit.so
	linux-vdso.so.1 (0x0000ffffbba75000)
	libboost_serialization.so.1.74.0 => /usr/lib/aarch64-linux-gnu/libboost_serialization.so.1.74.0 (0x0000ffffbb259000)
	libpthread.so.0 => /lib/aarch64-linux-gnu/libpthread.so.0 (0x0000ffffbb228000)
	libstdc++.so.6 => /usr/lib/aarch64-linux-gnu/libstdc++.so.6 (0x0000ffffbb050000)
	libm.so.6 => /lib/aarch64-linux-gnu/libm.so.6 (0x0000ffffbafa5000)
	libgcc_s.so.1 => /lib/aarch64-linux-gnu/libgcc_s.so.1 (0x0000ffffbaf81000)
	libc.so.6 => /lib/aarch64-linux-gnu/libc.so.6 (0x0000ffffbae0d000)
	/lib/ld-linux-aarch64.so.1 (0x0000ffffbba45000)
```
