Rollup merge of #93504 - solid-rs:fix-kmc-solid-stack-size, r=nagisa
kmc-solid: Increase the default stack size This PR increases the default minimum stack size on the [`*-kmc-solid_*`](https://doc.rust-lang.org/nightly/rustc/platform-support/kmc-solid.html) Tier 3 targets to 64KiB (Arm) and 128KiB (AArch64). This value was chosen as a middle ground between supporting a relatively complex program (e.g., an application using a full-fledged off-the-shelf web server framework) with no additional configuration and minimizing resource consumption for the embedded platform that doesn't support lazily-allocated pages nor over-commitment (i.e., wasted stack spaces are wasted physical memory). If the need arises, the users can always set the `RUST_MIN_STACK` environmental variable to override the default stack size or use the platform API directly.
