Refactor estimation of stack info table provenance

This commit greatly refactors the way we compute estimated provenance for stack
info tables. Previously, this process was done using an entirely separate traversal
of the whole Cmm code stream to build the map from info tables to source locations.
The separate traversal is now fused with the Cmm code generation pipeline in
GHC.Driver.Main.

This results in very significant code generation speed ups when -finfo-table-map is
enabled. In testing, this patch reduces code generation times by almost 30% with
-finfo-table-map and -O0, and 60% with -finfo-table-map and -O1 or -O2 .

Fixes #23103

(cherry picked from commit d99c816f7b5727a3f344960e02a1932187ea093f)

Add a test checking overhead of -finfo-table-map

We want to make sure we don't end up with poor codegen performance resulting from
-finfo-table-map again as in #23103. This test adds a performance test tracking
total allocations while compiling ExactPrint with -finfo-table-map.

base: Advertise linear time of readFloat

As noted in #23538, `readFloat` has runtime that scales nonlinearly in
the size of its input. Consequently, its use on untrusted input can
be exploited as a denial-of-service vector. Point this out and suggest
use of `read` instead.

See #23538.

Build vanilla alpine bindists

We currently attempt to build and distribute fully static alpine
bindists (ones which could be used on any linux platform) but most
people who use the alpine bindists want to use alpine to build their own
static applications (for which a fully static bindist is not necessary).
We should build and distribute these bindists for these users whilst the
fully-static bindist is still unusable.

Fixes #23349
